First of all thanks :>
Do you have any details regarding the glitch? I've been trying to fix it for some time now, but sadly can't reproduce it.
You're welcome :)
It always seems to be when I do big jumps or double jumps, it happens when I start to fall faster and I slip through the floor. It also happened frequently if I move forward and jump at the same time. I tried it in the tutorial screen but it didn't happen there I think, Hope that helps!
