i like the idea here, but the precision required is insane. i personally dont have the reaction time to make it past more than about 2 or 3 launchers before it gets too fast. if you were going to tweak this, perhaps doing something clever in the background to help the player out would improve the experience - like expanding the collision zone radius for successful input with each successful press so the player gets more of a window to act as it gets faster, and thus feels more badass.
audio worked well though. I always like a pitch modifier on something going faster! nice work!
