You're getting better at making games!
Marble Madness was a great game (although only the arcade game, NES, and Genesis ports -- there were plenty of awful ports). Likewise Super MonkeyBall was a great game.
I wish the controls in this would be more what they are in Marble Madness but unfortunately they are not, but that's not a take-away point from this game. I take it the controls are supposed to be part of the challenge.
