Wow fun! Super original game idea. I played this for a while.
There is a cheese where you can just push the other player and not have to do the constant back and forth. Also I found my self loosing the curser every once in a while, maybe could you make custom curser that is larger? Also no audio for me :/ womp
Even with all that I played this more than any of the other ones I have seen so far. So good job!
