Yikes! That escalated quickly :-D
I wasn't very keen on the WASD movement to start with, but when the number of enemies started growing out of hand, I started to appreciate the ability to keep circling them whilst still facing them.
Nice graphics style and good sound. A high score would have been a nice touch. So many games in the jam just complete and show an end screen before you've had chance to check the score.
Those enemies really go nuts in the end! Nice one.
You should have more ratings than this.
