In my first two attempts I killed the hero once by accident (the finishing move really does a ton of damage!), once because I didnt have any other moves left after filling the bar with almost 1000 points. It was only on the third try that it occured to me that the intended ending of a boss battle in a video game is for the boss to die after delivering a memorable encounter. I really enjoyed that this game took the theme much further than I had originally expected.
Great work!
