Cool game, the movement worked at ease. The player however was floating which obviously can be fixed easily. Good take to the theme.
A really cool game I really enjoyed the character movement. The animations were really cool. Great game idea. Cool sound effects.
remember to hold R, when you collect the diamonds, don't let go of R, it will reverse all your movements if you hold it until u reach the start again.
Try restarting the level.
I think, the longer you wait as idle, the longer it will wait when your in the process of rewinding.
