New Game: "Bust a move" + seesaw =?

I’m in the middle of making this game and I wanted to post it as is for some opinions. The game is like “Bust a move” on a seesaw (well its on a boat in the game, but its kindof like a seesaw phyisics). I wanna have enimies that you have to weigh down to make them sink or they’ll crash into your boat and tip you more.

Anyway, try it out, lemme know what you think or any ideas you might get. That’d be cool. You need flash player 8.
