Totally unplayable mess. Art seems very cool from the pictures, but hitboxes and getting hit are all over the place. Sometimes you rocket across the screen when coming in contact with an enemy. Sometimes enemies repeatedly bounce over the top of your hitbox without coming into contact. Oftentimes you sink through terrain with no warning. After a few hundred attempts like this you reach a point that is programmed so bad it's impossible to land on the platforms at all. Stay very far away.
