Cool stuff! At first I thought, that there is way too much keys to press, but the system actually worked quite well. The visual effects were nice and fit the style of the game. I found it a bit difficult to get into though, maybe because the screen is filled with effects and stuff from the very beginning. Maybe it could be a bit easier in the beginning, and ramp up in difficulty little by little? Also the camera is positioned in a way that when you stand in the bottom side of the arena, the wall blocks sight to the character. But overall, a nice idea that could be developed into something really cool!
