Yes, one of our friends also had this bug, but it seems to be extremely rare among players. Please let us know if you've managed to fix the problem.
Yes, installing the thing manually and then rebooting worked. I guess its some library that is not included in your game files.
It was pretty cool. Kinda trippy with the constant gradual scaling. The first few times I found myself thinking "Wait, when did I become big??" 😅
Since the scaling is so gradual, there should maybe be some more visual feedback reminding the player if you are currently growing or shrinking, like a little up/down arror next to the character.
Also, I'm supposed to dash-jump with shift+space, but that didn't seem to work. It wasn't possible to jump while dashing. Dashing while jumping worked.
