I had this idea for a game based on colliding worlds, inspired by the moba infinite crisis I play frequently.
So this is some form of dodge obstacles game with world changing abilities that change your players form helping you avoid things. My first entry into ludum dare :).

you can only pass through red, half/alpha blocks in the "shadow" universe.
the "bouncy" universe, makes you jump higher
the "small" universe makes you tiny.

The Controls;
Left & Right arrow keys to move
Up to jump
Space to switch universes
