In need of improvement.
I might just go back to square one with this game if I were you. By the looks of it, this game needs an overhaul. First, the graphics really could be a lot better. Great graphics can make even the worst game enjoyable. Second, the game engine needs to be tweaked/redesigned. Jump and movement physics need to be redone. The marble should have acceleration and deceleration, so that it actually feels like the marble is rolling. The jumping feels WAY off. Collision detection is somewhat poor. You have the makings of a potentially great game, but this definately needs improvement.
