Yeah, the attack distance is a little off: sometimes punch effects appear when you haven't done any damage. I gotta hunt down why that is.
The damage thing is an easier fix because I made them variables. I've noticed matches tend to go for 2 minutes, which is a tad long considering most fighting games tend to have a max fight time of 99 seconds. I'll see about increasing fights
You can block with the "T" button, and 3 punches in quick succession give a heavy punch, 3x the damage but has a cooldown.
