Could turn out good, could turn out lousy. Honestly, it's too early to really speculate (kinda expected from a concept build though). I tried playing twice, couple things worth mentioning.

Description: Might help if you explicitly mention that this is currently only a map to navigate through, based on my quick read through before trying it, I expected npc's/items with minimal interactions

Corridors: My first game, the second corridor I arrived at (up from the bottom left corner) was a 'solid wall'. This prevented all progression and I needed to restart. While the random corridor concept isn't bad, you're probably going to want to ensure that every build can actually get through every corridor (penalties are welcome) to prevent being locked out of the critical rooms, or in the case of my character, locked out of the game.

Character creation: for skills and stats, having mouse-over tooltips explaining the stats/skills would definitely be helpful (or descriptions next to them if you dislike tooltips). Making it so the user needs to navigate to the skills page multiple times to check what the skills cover isn't player friendly.

Character stats: Character 2 was female. after playing around with the random stats, the shortest I was able to get her was 5'6", with the higher end being 6'2 or 3. Might want to scale those down or at least expand the lower end. Alternativly, give the player X points to play around with to have thier victim... err... character start closer to the way they want it to. As a previous poster suggested, a few options for premades is probably a good idea (some will want to tweak thier character more than you currently allow, others won't care in the slightest and just want to get in and start transforming/traumatizing the character)

Character clothes: gauze should probably be banned as an option from things like shoes and purses (unless the character -really- doesn't like carrying much gold)

Theoretical sexual interactions: May want to have the option to remove certain types of content. Substancially more work adding in options, but will increse the draw for those who are attracted to a specific gender, the herm only brigade, and those who feel like disabling certain genders/pairings for other reasons (scenarios that amuse them, RP purposes, simply being bored of certain things, etc). Isn't nessassary, and if you're trying to do a reenvisioned trap quest it might might not be the game you want to make (which is the most important part), but it would likely increase the appeal.

Controls: previously mentioned, but agreeing that hotkeys and/or standardized placement are a must for navigation

Load times/Saves: previously mentioned, but something definitely isn't right with your transitions. Based on the fact that reloading seems to regenerate the map and the transition slowness increases as you explore more, I'm guessing that as you approach an area, it's checking if the area is defined, and if it isn't you're looping through options to find one that hasn't been placed yet. Assuming that's accurate, it will run -much- smoother if you generate the entire map when the game starts and only need to wory about calling the matrix after that. If thats wrong, you may want to ask around on the forums to see if an experienced dev can glance at your code and see whats slowing it down.

The images look promising, and I look forward to the next update. Having a fantasy like character creation and being dropped in a seemingly modern world was weird though.

Here are a few points you might want to consider when you touch it again.

Transitions between rooms take really long and the link to proceed is always somewhere else. I don't think, I would have much joy in the constant search for the link when nothing happened at all or I just want to go to a specific place. Maybe it's just my browser but the loading while travelling is just too long. Having fixed buttons or using keyboard input should be easy. I hope you can figure out how to reduce the load times.

Add a random character button or have a few ready made to choose from. I'm sure there are more people like me who don't want to drag through that kind of character creation and would be just as happy with a random bag from the rng.

I am watching this.

At this point it's hard to call this game even an early alpha. There's basically no content at all. Apart from a rather plain character customization there's just a map with the names of the locations.
The idea of a fantasy dugeon full of sex could be entertaining but there has to be ANY content.

why even post it if it's discontinued at the concept phase?

v0.01 concepts which were discontinued, is bounded to have no love. What is in the 20MB html is 1) character creation, which isn't fancy, 2) clothing system, which isn't completed and 3) a map layout, which is so far the only thing I find worth to take a look. It isn't fancy, but it is neat and clean. That said, it is probably at stage v0.0.1 atm...
