Really funny concept and clever use of the theme! I had a fun time with it!
I think it would help if there was an indication that enemy towers are about to fire, as you have to get pretty close to fire on them and some of them fire huge objects.
Also, I couldn't tell if it is happening or not, but it would be cool if going in the opposite direction of your lean helped stabilize you quicker, like trying to keep your balance instead of just waiting for it to rebalance on its own.
Really great job!
