Very clever idea and I loved the particle effects when dying. Also, the music is really cool. I think this game has a lot of potential if expanded after the Jam with more time.
Good Job!
Few suggestions if you plan to work again on this:
- I would add an animation when rotating the cube (I think it would really improve the feeling).
- It would be cool to control the height of the jump with the duration on which you press the button.
- Maybe a small onscreen tutorial to explain how to rotate the cube at the first platform.
Anyway, a really nice entry :D
