Bug report; I'm on chrome, dying and pressing 'replay' got me this:
I reloaded the page, died and pressed replay, and got this lol:
(the screen shot up into darkness, pulling my cursor with it)
Third 'replay': went fine
Fourth: I was allowed to place one block, then shot up to 448 again
Fifth: went fine. Not gonna log more lol. For some reason, though, pressing 'replay' turns off all sfx, which sucks cause they're really fun.
