Simple and effective.  Not sure if you intended the player to have to time their spacebar press, I ended up just holding the key in order to bounce. Bouncing was fun.  I also like how the player rotated in midair when jumping.

I did it :)

10/10 best game ever

I like the surreal quality to the exploration, and the bounce mechanic (maybe consider having a special sound that plays when you pull off a bounce, just to make it that extra bit juicier). I wish there had been more to do and explore, but I know time constraints are tough. I would play a longer version of this game, though!

The surprise is really great. Good job.
