Really fun idea, though i wish the enemies would deal more damage since its pretty hard to die while not trying to. Also the webgl version on your page doesnt really seem to work, could be a me issue but idk.

I think you probably got lucky with your enemy lineup
Especially if you didn't encounter green swarmers, they are absolutely brutal.
If the WebGL version isn't working, try refreshing the page and if that still fails it might work in incognito. But it seems you got the windows version working, so that's fine.
