I like the graphic of your game, it has his own identity.

The controls feels too floaty to my taste unfortunately, also, when colliding with the side of other box colliders, you get sticky to it.

It doesn't seems there is a way to restart the  level by your own. Wich is unfortunate when you get stuck between two wall (in your first level)and nothing has be made, so the player can get out of here.

The game over button, doesnt works.
