I wasn't even able to play because the mouse was lagging behind my actual movements by several seconds, even just on the title screen, and trying to fix the game just crashed it completely.
The game seems fun, but also seems to be either horribly unoptimised to the point not even my fairly chunky PC can run it, or unable to play nice with Firefox for very long... and I can't even test the latter because there's no non-browser version of the game, and I'm sure you can understand that downloading a brand new browser like chrome just to play one game is a little overkill.
