The restart button works just fine in terms of being a simple scene reload, however I recommend playing in full screen because if you dont that entire part of the game can sometimes be blocked by the extremely long title of the game jam. That's the only instance I've found of it not working - if you can tell me of another way I'd be keen to hear. The white triangle is actually not intended to work so the bug is that it actually is rotatable one time on the first level! Thanks for playing!
