Great, game. Hands down. I generally despise Ren'Py because so few of them beat your average hentai manga but this game has a whole swath of them beat.
-Solid Art, I really like the style
-Solid Structure. I can't praise this enough, so few Ren'Py get it right. Even without the descriptions (which, I very, very much appreciate) the choices are realistic and logical and because of that the flow of events is fairly intuitive. furthermore, it's immediately obvious exactly what the game's branches are and how to get there even without the (again very welcome) in-game descriptions. Not once was I just clicking through days wondering "where the F*** is the content?"
-Good base of content, With this many scenes/choices available this early I have high hopes that this game will go places. Even in it's current form it just needs a couple good endings and it's already up their with the best of the Flash and browser games. I can definitely see a later version, with a year or so to build up a following competing with the top games on this site.
-Fertility system.
1. Fully integrated
2. Simple enough to play well, complex enough to be fun/interesting. It's really really nice to see a game go beyond "one pump and you're knocked up, 2 days later baby out." You're system has a good balance of predictably and random chance to really capture risk and tension. The fact that you're already implementing consequences in scenes makes it even more exciting.
3. The only Improvement it really needs is some hot dialouge to really capture the idea of "playing with fire" and it's set. Add that, and It will be in the top 5 fertility systems i've encountered.
-Good tone. I'm interested to see how far you go down the "loss of innocence" road, I hope it's not to terribly far. It's nice to see a corruption type game without excessive NTR or completely mindbroken girls. It's pretty sex-positive, and the MC is pretty much in control 90-100% of time. I also really appreciate that you can, essentially, play vanilla for a while (or cheat) and then jump straight into the "higher tier" content rather than being forced to go through the tired progression of "strip, some kind of oral, anal/vaginal sex, complete insanity). It feels more natural and less like "and here i check the story flag" furthremore, where you do choose to use event progression, you've done so in a pretty natural way with good pacing.
Improvements/suggestions:
-somewhat faster stat gain and/or ways to progressively improve stat gain without cheats. The cheats are awesome to cut down on grind, but having that integrated into the "base" game would be great.
-More text/dialogue. All the scenes have great bones, but to really capture replay value it would be cool if they cycled through a few different passages. That way, even though the art would be the same each scene could play out slightly differently for example: progression with each BF scene would give the feeling of a growing relationship without requiring totally new scenarios and art (though i'm not gonna complain if you add more!!), 3-4 different sets of dialog to give the impression of different customers in the bar/spa.
-Maintain the relatively light tone of the game! Lots of these games get way to full of themselves and/or pretty depraved. This game right now, at least in my opinion, has a really good balance of "have a grand old sexy time" without laying on thick with NTR or stripping the MC's will/mind/whatever. "I had a really crazy time in college" plays a lot more enjoyably than "that time I was a sex slave"
-Depending on what the events are, some hero content could be really cool. I think you've got a good MC on your hands and that could be a nice way of fleshing it out. someone above mentioned yuri, maybe there could be a few BF/GF options drawn from exploring the other students and missions?
Keep up the good work!
