I like the game but I don't understand why the space bar is the jump key and not the up key. What is the up key for in this game? It is difficult to fight when you are using the the c key and the space bar for fight and jump. J/K is also a bad combination because I then have to place my left hand on my mouse pad on my laptop. I personally find it easier when the fight key is used by my left hand and jump is the up key. I appreciated that you avoided the z/y because I have a QWERTZ keyboard.
