Enjoyed the game! Might just be me, but I feel that the hit box on the rockets only is a little too big.
But, I may just be bad. The other stuff felt fair though. I know it's an endless runner (cause 48 hours), but I'd be interested to see how it'd play with levels where the plane is broken differently (tilts left sometimes, rights sometimes, down, up) and you have to get to the end or something.
