The visuals on this are really nice and the interpretation of the theme is great. The music is also good. I did experience some garbled music after I'd been playing for a while (linux, firefox) but didn't seem to have other performance issues. Controlling the character by having them walk towards the mouse felt awkward to me. I think I would have preferred to have movement on the keyboard and aiming on the mouse. Especially since, at least of firefox, the character stops moving if the mouse leaves the game's viewport. It wasn't clear to me what the charge mechanic did, it seemed to be identical to a normal swing.
