Thank you for playing.
as for the bug, at what level did that happen? and is it like you can't move at all? or is it that the player character animation is stuck on falling, if it's the former, then I'll look into it because I did encounter a similar bug in Susurrae, if it's the latter, that seemed to happen when the player is falling but close to the ground, usually at the start of the level, jumping again would fix it.
