Honestly awesome premise. I love the idea of playing essentially as bey-blades. I also didn't know these bugs were called doodlebugs! From where I'm from, they're called Rollie Pollies!
I think this game would kill as a multiplayer game (couch co-op), kinda like a sumo competition! My biggest critique is that at first I couldn't really tell why I was spinning the wheel or what it was affecting in the game, maybe that info could be given in the controls page? Great job guys!
