So far really good. The 69 cheating scene was really great, and I've never seen anyone else do that before, so props for that.
There are a couple of issues I ran into (one is minor/aesthetic, one is a bug). The interactable at the beach is incredibly hard to see. Maybe use something else against the sand background.
After the costume party, The Ren sprite (and character sheet) doesn't leave the party for the rest of the game. It doesn't affect the gameplay or scenes in anyway, but there were a lot of times when I ended up running around with 2 Rens in the party. It made for some strange instances, lol.
