Very slippery movement, and WASD isn't implemented (S and D work though)? That means you can't move and press space at the same time, while also having a hand on the mouse.
I don't see how the theme applies at all, either.
I checked out some of your other games, though, and it's clear you have some fun little ideas. Game jams can be really hard with the time constraint, but keep at it! :)
