Hello, I gave this a go; I like the art and concept a lot.
I have had some challenges.
1. The jumping: I wasn't high enough at first; it wasn't clear that if you move, you jump higher... sometimes? Also, I don't think I jumped high enough a few times, but still I sort of teleported on top of the ledges...
2. At the saxaphone aim and shoot game, due to the itch overlay on the right when the items falling down where too far to the right i would click on a itch overlay making the browser navigate elsewhere so i got stuck there, i don't think ti's the game it's the itch website overlay.
last thing which just looked a bit odd is that when you're on a ledge you kind of float just above it, your nost standing on the ledge but 2 or 3 pix above it, it looks a bit odd.
Again, cool concept and good luck!
