Hi! Thanks.
Maybe you got hit by a rock or a round mob or something like that. The player is then thrown back according to the laws of physics (conditionally, of course). You can even do it on purpose :)
As for music - definitely not, because I've been catching all the bugs, I've probably played it 100 times. That definitely didn't happen. Well, maybe you're a particularly lucky tester :)
Anyway, thanks for your opinion :)
