It's an interesting game, the controls could have been explained a little better, since it took a minute to figure out that the mouse did something. Couldn't beat it though. It's an original idea.
You can use the mouse left click, right click, space bar, X, B and Y on the gamepad.
Except moving, it's the same and only action you can do: switching colors.
My goal was to not explain anything directly, many jam games are simple enough to intuitively be played.
