Ah I see what you mean. Yes, so the reason that may happen is there's "on ground" detection on the girl character. It's got a slight delay on it so if there's a gap under her for too long she is "falling". For now to prevent her falling forever in that case, she will die if falling too long. Of course this can not always be the case, and in a full released version would be much more tuned. However for now, just working the manhole cover into the hole with as small gaps around it as possible will allow her to walk over it. Please do remember it's a 9 day game jam, and i only used a few hours in 7 of the days, thanks for playing! I hope the rest of the game was interesting enough for you
