Constructive Criticism (one that plagues 99% of visual novel style games): Make the cumshots more than one frame. I don't know of any cumshots that's one spurt and it's over. It can be varied based on the character, too. The old dude pretending to be blind? 2 spurts. The step-father who's got a harem? 5 spurts. MC? Standard 3 spurts. Etc. etc. Just do a frame with the cum, then add a frame with a bit of cum on her body (or wherever) with none cumming out of the dick, then another frame with another spurt. It shouldn't be that difficult, honestly. The gloryhole scene in The East Block is a great example of how cumshots should be handled. It's really a pet peeve of mine that cumshots are so short in these games. One large spurt and everything comes out all at once? Dicks don't work like that.
Now that the constructive criticism is out of the way, I love the game and story so far, so don't take the criticism as a bash of the game. Like I said, 99% of these games are like this, and I think it could be an incredible improvement.
