Cool game, and well done for making all the artwork yourself! I found a weird bug with the ALT key where it would 'unfreeze' the game but not unmask me. I had to press ALT again to unmask. It kept on happening so it got a little bit annoying xD
Thank you :) The freezes shouldnt be happening at all, it is a problem with the WebGL version but only in minimized mode. So if you maximze it, it should be fine ;)
