Gravity Warp

Play as a cube man who has no legs and cannot jump, but uses his surroundings and powers to change gravity to (insert story part here).

Black is a platform you walk on.
Red is spikes that will kill you when you touch them
The key is a key to open a door
Yellow is a door.
Green is the stage exit.
Blue is a jump/bounce pad.
Purple is (obviously) enemies.

Controlls are

A+D to move, (or Left arrow + Right arrow)

Please keep in mind this is my second game using C# or unity.
