Very good game!
I saw you have a moving platform at level 8.
I also have such a platform (not user controlled), but I have big problems that the player can stand on it. No matter horizontal, vertical or oblique, the player moves, flickers, etc.

Maybe you can help me.
What’s the trick to work around this “bug”?
