its infanite as far as i can tell...
i've left it on for hours (i pressed "p" during replay, after you stoped moving, pressed "e" then "p" again, so instead of replaying it after the frames run out, it continues, and it hasn't moved at all since, even as i type this your tori stands in an akward position for what looks to be the rest of its life...)good job lol
ill let it run over night and i'll tell you tomarrow if it does, truely last forever...
