The game has very sturdy controls. I can do what I want to do without much trouble. That is something I don't see in very many games of this type. However I don't see a progression of challenge. Each level is about just as challenge as the previous. This game can become much more interesting if it tested your abilities in a fun and challenging way. I.E have there be an obstacle that is not only challenging, but have the overcoming of said obstacle satisfying.
