Honetly, very solid overall. Has quite a few kinks to work out to flow better. Pun intended. As the core loop of gloryhole is a bit janky and lacks variety. But, that seems implied to be worked on.
The story is very... there. Not bad, not good. But it works fine. Could have gone with many variants. But for what it's worth; it functions well.
That said, I do feel like there could be some more oomph to the pussies... Granted, I have no clue if you plan to have any lesbian scenes at all, or futa ones where it is visible. But it does currently feel a little "just there". So, could do with a little more love. Granted, unlike most other games: It's not too far behind detail wise. But, it does feel like you plan to add a lot more oomph dick wise.
Anyhow, if you want any advice or to spitball ideas, let me know. I've got quite a bit experience with this stuff. I did create Hole House after all :P
