You know, I like this. It's a very raw game, in the sense that I feel like it doesn't find itself needing to be particularly palatable. There are no checkpoints, there are some red herrings and false paths that lead you to death, even just the concept of the bouncing island is fun, if only ever so slightly relentless. The game is tough, but it's clearly designed with intent, and I like that. It's not really hard for the sake of being hard, you know?
Anyway, congrats on submitting for this game jam! Be proud. I wish you the best!
