this is a fun idea with some great enemy ai! the controls were a bit hard for me, since O and space with my left hand was a bit awkward. i think wasd, O, and space would be fine though. my only other note was the first time i played, the opponent looked like my character and this was very confusing at times. making the opponent more visually distinct (maybe making them a different colour?) could help with this. overall, really well done!
