Found, maybe, a glitch? Got up to 301 Kg, missed a jump on a barrier and fell. But she didn't get up after that (Which is comprehensible had it been real...). Have to see if it happens again, tough. Nice game, all in all.
Yeah, I get what happened, it's a bug. Basically, hitting the barrier interrupted the sequence by exceeding the maximum playable weight and it got stuck in a deadlock. Anyway, I've already fixed the problem, but I'll keep testing it and will upload the fix tomorrow.
