The idea is nice, but you have to work on it a bit:
1- In the instructions, you forgot to mention the game controls;
2- Insert a few more MJ reactions, like crotch grabbing, hat lowering or moonwalking on the skate. It feels like nothing is really going on;
3- Theme - MJ catching scattered coins and escaping rocks and trees isn't reeealy an attractive premise. Try changing the coins for kids, or the obstacles for fans/priests/zombies, anything. Plus, You could make each scene song-related.
But good work, nonetheless. Keep on with the good work!
