Version 0.02a contains some small improvements and one bugfix.

When using the fist, the hydraulic charging sound now only appears when using charged attacks. As a result, quick punches now sound better. Additionally the charge up time for the most powerful punch has been increased slightly to improve balancing.

Other than that, I managed to fix an ancient bug involving
the collision detection of rockets. For a long time I considered this bug to be an unsolvable mystery, but finally I managed to find the part of the script that was responsible for causing the collision detection errors with specific enemies.
