This was pretty well presented. Gets chaotic quickly, although the recharge mechanic feels like a break in the action and makes the player want to stay fairly central despite having a fairly large arena to play with. Perhaps power could be a form of collectable the player must seek out around the arena to force them to move around more? The art is good, from here I'd try to improve on the mechanical balance and "feel" of the weapons and attacks. The menu + splash and meta considerations are all really well presented. Solid!
