Calibration Error
by apolloseven

Calibration Error is a comedy/sci-fi/smut story of science gone wrong. Hijinks ensue after an unlicensed, inadvisable experiment that leaves the main character in a body not quite normal. Will you manage to return to your male body? Or maybe you'll end up having sex with anyone around you who breathes. The choice (as long as the choice is one I wrote in advance) is up to you!


Calibration contains 250+ 3D renders. At this point the game is one update away from completing Emily's storyline. If you like the game and want to help make it better, consider contributing on Patreon. The game will always be free and all updates released to everyone at the same time.



The newest update is .75 which completely overhauls the formatting of the game and doubles the number of renders. Hope you enjoy it!




Complete formatting overhaul.


130+ new renders! Almost double previous release.


Removed TF Card Battle. It is now a separate game.


Minimal story content


Development Plan:

.8: Finish Emily's storyline

The game branches at visits to Emily's lab. Essentially it's a tree that looks like this:


                                 / \

                               / \ / \

                             /  \/ \/  \


The important thing to note is the branches merge together. So the outcomes grow linearly as the game progresses. However not every branch merges, there are hard "walls". Choice 1 results in 2 outcomes, choice 2 in 4, choice 3 in 6, choice 4 in 6, choice 5 in 10. Choices 6-8, which are to be released, will end up with 12 total outcomes and endings.


Just pick different choices in the Emily scenes for different results. Although some choices lead to the same outcome, they all have unique text on the way there. So if you really want to see everything, choice 7 has 12 separate unique passages that can result.


The psych professor's scenes are accsessed by losing the TF Card Battle game. Content gated by winning will be added in a future update.


Pasage advancement is now handled with the arrow keys instead of any key.

Note: I've only done one playthrough to get the gist of it, but there are multiple endings that depend on your choices.


I play card games off-and-on; I'm not fantastic at them, in fact I'm mostly bronze tier. However, I am good at theory, and can say this: you have no reason to pick the flirt or submission cards.

The game wants them to be the more powerful versions of the normal ones, but that doesn't pan out. The cards that are actually strong are the draw cards. A draw card means more actions in a turn because there is no limit to how many cards you can play. They allow you to fish for more cards and move through your deck faster, which also means resetting it faster. If a card has a draw on it, it is worth more than any of the others. Paranoia is beyond OP at its cost, with an always useful defense plus the cycle draw.

With enough draw, it doesn't matter if you have those 5 +1 int cards, you'll get your good options every turn anyway.

Even at the final boss, I had enough draw and int cards to clean them out.

The game even tells you taking the flirt and submission cards is a bad thing by taking away points. And most of them are just so you can get more flirt and submission cards, which you don't want!

Also the draw cards counteract the effect of those flirt and submission cards padding your deck out, so they're just an annoyance, not an actual tool usually.

Altogether, it is basically saying that becoming a submissive bimbo is a worse way to fight than to be a genius. Which, while that is kinda my wheelhouse, I don't imagine was the purpose. The card game could use some mechanical changes or added depth, in addition to major buffs on the flirt and submission cards.



Oh and, the story's alright. Kinda repetitive when you end up skipping right down one character's path and the same things keep happening. Interesting though.

Reminds me of Total Recall.
Progress on this game is steady and well rounded.
Author splits dialogue adding a "mandela affected" story line offering variations on a theme. 
This game already has 10+different variations as of this review.
Dont like the card game however if the point is that games make people retarded then its a good point.
(B+) (7-10) (***/****)
Will play again.

It was a pretty fun play, I just personally think that the "card game" takes away from the story so even though there is auto card picker and choosing to lose altogether, I still find it distracting from the overall game.

So far, this is a very enjoyable story, with nice renders and good, sexy stuff. Please finish!

Played through available content on build 6.2 (08-27-18).

The first chapter is complete, and while the larger story is unfinished, the chapter is mostly self-contained story. Initial playthrough is short (30 mins) and each subsequent playthrough is much quicker. Many different branches to explore, and the art/imagesr are very well done.

Only drawback is that the choices you make generally don't really seem to relate to the results. While the story is enjoyable, quick, and (mostly) lighthearted, many of the choices lead to somewhat random-seeming results. It's fun to find the many different branches, but it's really just trial-and-error that will lead you there (and a few endings take some REALLY odd choices to reach). Fortunately, the creator includes a list of all chapter 1 endings, and, even a sotyr-branch map, to help you find all his content.

One of the better short-story games on the site, and something we can only hope we eventually see a finished chapter 2. Very worth an hour or two of exploration.
