This was fun for a few runs, but I ended up giving up before credits because it was taking away more than 1 health each time I got hit. I'm not sure if that is intentional, but I had 3 health and got hit once and died, where I was expecting to still have a chance to get away and finish the game. Also, after restarting the game, the music stopped and it was silent except for the sound of the enemies hitting me.
The gameplay of running around really fast and dodging the enemies, sending them flying far past you and watching them turn around was more fun than I was expecting. I might come back to this later and see if I can finally finish a run. Nice job!
