Zeta Wave

A polio vaccine trial goes wrong in 1931, and the descendants of the students in the trial are all found to have the zeta chromosome. Every time the carrier of a Z chromosome has sex, he or she physically changes to the opposite sex. It is a biological discovery that will change the world. How will it change the world? That's up to you.

Story #1: The tale of Billy, a high school sophomore and all-around Boy Scout, who discovers he is a Zeta carrier for the first time. How will he deal with this ability? Will he come out to his friends, or will he try to keep it all a secret? 

Length per Twine UI: about 166K "words."

Version va0-011 (in progress)

  • Fixed a spare DIV tag when you examine yourself as a girl on Day 12.
  • Added new dialogue on Day 3. If you are open about being a Zeta, you shouldn't be so worried that Dot will talk.
  • Added a new paragraph to describe bathing on Day 12, if you are secretly attending Boy Scouts as a girl.

Version va0-010 hotfix 1

  • Fixed link on Day 5 page, scout meeting, choose "volunteer" or "let someone else." Invalid variable method caused a crash.

Version va0-010

  • Completed almost all of Day 12, the first day of your scouting trip.
    • You may attend your original troop's trip, or the opposite-sex troop's trip if you confessed to your scout master and joined the other troop.
    • There is a mandatory transformation if you did not do the double-TG on day 11.
    • There is a possible optional transformation if you are not in the right shape to attend a scout trip that you're entitled to attend.
    • There are three superbonus decisions on this day. This day will be fairly influential to your final form.
    • The only missing scene is the "go to sleep" scene, which will contain another choice in certain paths.
  • Fixed an undefined reference to the gym teacher if you stay home from school.
  • Fixed continuity in the Double Secret TG scene. The Pep Squad and Marching Band scenes were mixed up.
  • Fixed a reference to SO's bra being too large; it isn't necessarily so.
  • After the art room makeout scene, the game will now properly re-assess the player's school schedule.
  • Various stray DIV tags cleaned up.

Version va0-009-hotfix

  • Cock size now prints correctly on the first page. It was not being set until the first transformation.
  • Name and opposite-sex name now print correctly on the Character page as soon as they are set. Nicknames are now included.
  • Variable name error fixed on "shoulderbonus." It was missing the $ (variable indicator).
  • Typo fixed.

Version va0-009

  • Shoulder width should now function properly, with bonuses.
  • A bug with vocal range has been fixed and it should now register properly. It will also change quite a bit faster than before.
  • A bug with height not being calculated correctly has been fixed.
  • A behind-the-scenes feature has been added to skip forward to Day 8 under a variety of different conditions. This is not available to players and is only for testing.
  • Day 11 is now complete.
    • You may proceed after your transformation (if you had one).
    • You can see the results of your Double Secret Transformation (if you did that). Your mom will give you an outfit to match your new sex, and everybody will see you in it.
    • You can talk to the visitor at the school. This is only available (and indeed mandatory) if you have given an open interview to the school newspaper.
    • You must confront the bully after hours. You will have various options for doing so, depending on the choices you've been making.
  • Various fixes to other minor bugs, broken tags, and continuity.

Version va0.008

  • Day 10 is complete.
  • Day 11 is about halfway done. It will end roughly around 4th period or lunch, depending on the path.
  • You can meet your Friend or SO in the hallway after first period for some emergency smooching, but only if you are trying to get back to your starting sex. Your SO may or may not be willing to meet with you, depending how you've treated them.
  • If you do the emergency smooching, you may transform in one of the following classes: Gym, Marching Band, or Pep Squad. Whether or not people notice this transformation depends on your status (if you are in disguise, if you are open, etc).
  • There is a second transformation that can occur on Day 11, with disastrous consequences, but I'll leave you to discover how that occurs.
  • The meeting with your SO on the morning of Day 8 has been slightly refined; there is now a distinct option that occurs if you've never bothered to contact your SO after the first day.
  • Numerous bug fixes and broken tags fixed.
  • New feature: some game choices now provide a super-bonus to a single stat (height, strength, cup/cock, hip/shoulder). They are not labeled by design. These super-bonuses are available at all times — unlike the regular physical bonuses, superbonuses don't care whether you are the correct sex or not. This was added to give players slightly more control, but also to make sure the points kept pace with the pace of the game. In order to deliberately obscure the superbonuses, they will not be reported as part of your regular daily update; instead, they are added in secretly right before you transform.

va0-007

  • Numerous broken
    tags and italics fixed.
  • Numerous typos and incorrect pronoun variables fixed.
  • Bad story path identifier fixed for reading Shakespeare when teamed with Harold and Ray.

va0-006

  • Various broken DIV and italics tags repaired.
  • Broken link leading to Marching Band (FTM) has been fixed.
  • Declaring you don't want to kiss boys (or girls) now correctly results in adjusting attraction by -99.
  • Cock size should now print correctly.
  • The sex of the gym teacher has been fixed on Day 8.
  • Dead end has been fixed (don't tell anyone, keep secret from SO and scouts).
  • Day 9 is now completed.
  • Your group reads your scene from "As You Like It" in English class.
  • You will be able to read the results of your newspaper interview and discuss it with your Friend.
  • You will overhear students discussing the article in class.
  • Mom will buy a purse or a wallet (depending on sex), which you can accept for bonus points or reject.
  • Day 10 ticks over, but has no content.

 

\va0-005

  • Fixed some continuity errors in newspaper interview.
  • If you made out with your SO on Day 8 and transformed before school, you may now try to make out with your Friend, hoping to change back.
  • Another bonus-point activity is available in Bookkeeping and Geometry on Day 8.
  • You may now no longer choose to call your Friend to report how your appointment went. You will, however, tell the Friend at lunch.
  • Scene restored: shopping for Scout uniform, provided you are joining the other group and you are flipped to opposite sex. Otherwise, Mom buys the uniform without you.
  • You can now choose an article of clothing to replicate in Home Ec. The article depends on what you're wearing: what sex you are, whether you went to the Art Room with your SO, etc.
  • Revisions made to the Update routine. It should now be possible to run the day-end Update on a day where you transform, without getting double points.
  • Fixed a problem with the CleanReturn passage. It should now reset to "continue" after a custom link name is used, even if the custom link isn't clicked.
  • Completed Day 8.
  • Day 9 has begun.

va0-004

  • Added additional footnotes for hot dogs, homework, and the nature of education in the 1940s.
  • Fixed missing parenthesis during doctor's visit.
  • Fixed date alignment. The correct date was not printing on Cycle 0 every morning.
  • Corrected the Schedule Selection code, which would produce the wrong school schedule under some conditions.
  • Corrected Day 7 phone call ("news about appointment") with SO to include results from your date with SO or with Friend, if this was not already communicated on Day 5.
  • Removed the scenes where you shop for a new scout uniform, as they were interfering with another scene. They will be replaced to occur at a more convenient moment.
  • Corrected the flow of Day 6 so it is possible to work on the fence (or on housework) and get your bonus.
  • Added more player choices (how to inform Dot; how to comfort Dot; bathing again) that add more bonus points after Day 6.
  • Full bonus points should now be available on some activities that were incorrectly granting 0 bonus.
  • Upon meeting your SO on Day 8 before school, your SO is happy to see you. You may initiate another transformation if you are "back to normal."
  • Fixed missing "continue" link during newspaper interview.
  • Various other minor bug fixes.

a0-003

  • Corrected continuity errors in the Gary and Judith dates.
  • Fixed some broken links (particularly Betty + shaving).
  • Day 7 has been completed (doctor's appointment, tell friend or SO about appointment).
  • You may begin Day 8 with an early-morning transformation and self-exam.
  • Transformation self-exam on Day 5 has been modified to better fit the new shape tracking system and bonus points.
  • Added a positive SO response in Marching Band and Pep Squad to include when you have phoned your SO and confessed your condition, but you have not made a date with anyone. The negative SO response should only happen when you have not called at all.
  • Fixed some repeating text in the Bully dialogue on Day 4.

a0-002

  • Repair of various broken links and tags
  • Some mandatory events have been turned into choices. These choices will add bonus points to various body dimensions as you transform. Some of these activities are noted during the points update, but not all of them.
  • The points summary now states that accumulated Masc/Fem points will only affect you after your next transformation.
  • Day 6 has been completed (scout meeting, working on the fence [if you skipped scouts], contacting your SO [if you had a date with your friend]).
  • Revision of Character page to show body-region bonus points.
  • Fixed a numbering error on the Cast List page and added a few more cast descriptions.
  • Added "dark" mode and revised color scheme of "light" mode. There is now a place to choose initial settings and test the various game color schemes to see which you prefer.

I confess.. I was a little bit reluctant at first to play this game but after the raving reviews I want ahead and gave it a try, and then another try and then replayed it some more. I have another confession, I've become absolutely hooked on this game, the story, the detail to choices and outcomes,.. 
If you're like me and are a bit hesitant because of the description of the game then all I can say, give it a try!

I absolutely love it and can't wait to see how things unfold <3

I absolutely adore this game! The dedication to historical accuracy in all facets of the game is simply wonderful! There are some bugs that seem to creep up as you play (When I went to the Scouts as a girl, it broke the game and I had to backtrack. Certain events don't mesh with your appearance, certain others reference paths not taken, the scoutmaster's wife said she was going to take the two of us girls to a side area to bathe but I ended up with the whole troop), though nothing dreadful or disastrous for the most part. I am extremely excited to see this game continue to develop and I'm kicking myself for not having tried it sooner. Thank you to everyone involved! You've made me a very pleasantly surprised girl tonight! <3

Hey I've heard this one before.
Some obscure old movie with that as the premise.
Will update this review when the game has more to it but the premise has me intrigued.

Update for Version 0.02:
This is a lot more than a version .02, more like a version .20.
Still not a ton of content but the story is developing niceley.  I assume this game is based on the 90s(Early 2000s?) movie Zenophilia, which explores the same themes and has a similar premise(but is SFW)

Update for Version 0.09:
Never before have I been constantly checking this site for updates to a particular game before.  The narrative is fantastic and I really can't wait for the rest of the story being written here.  One of the best games on this site even with only a part of a part finished.

It's fairly enjoyable, and I really like the fairly unusual setting, but I would give a very strong content warning for anyone with any amount of dysphoria. It's really hard to get through as much as I did, and I would expect the same for anyone else with it.

I like it so far!

EDIT v0.2: This game looks more and more interesting, keep it up! :D

EDIT v.08: I'm enjoying this game more and more! I've made a shout-out on my Patreon, I hope it'll help you being motivated, you deserve it! I've read on your blog that, sometime ago, you were disheartened about a game who received only 5 comments. Well, the vast majority of people do not comment, but I guess many are loving your game!
