This is a very interesting game. It's good to see one of these hentai games actually put in some effort rather than just rinse and repeating the same formula over and over again. I actually found most of the databank entries humorous and entertaining, worth the read for sure.
Haven't looked through the reviews, so forgive me if I'm repeating someone else but a gallery option would really make it better, I think. Like, if you beat it you can unlock a gallery of the H animations and so on and so forth. You mentioned power ups, so I hope they include some extra moves (you know, sliding, dashing, air dashing even etc... don't be afraid to copy some Megaman X moves)
Overall this is pretty solid and I'll be probably end up being a patron of it, if only to support the concept of these hentai platformers with some actual effort put into them. All in all well done, will be looking forwards to the complete game.
