The only big problem I've had so far with various tests down is getting through the floor and through the wall. This problem is more prominent in places like being caught by a cat next to a warning triangle cone, being transformed by black latex at a wall, and Kling being transformed by Wolf King spikes.
You understood it correctly, eh ......... I haven't found any other possible problems, and probably because I'm only in the player's perspective, but that's enough.
Good luck with your future endeavors!
Oh......... Damn, I forgot about this, some boxes I do not know if there is no collision volume, the player can still climb up, resulting in their characters hanging (usually, this thing happens on those yellow boxes)
