If you're too wide and enter a screen transition where there's not a lot of room to stand where you'll end up, you'll get shunted back- often into the screen transition again which can cause some weirdness. Managed to get caught at the exit (coming at it from the right where the spike is) at max weight and while i was trying to wrestle with the game forcing me back a screen, i managed to jump and grab a platform then somehow trigger the screen transition? This left me floating in midair as if I was climbing an invisible block on the new screen.
Also, the key shortcut part of Plato's Cave is jank as hell and needs to be extended a bit i think- entering from below with the key means the door opening keeps shoving me into the corner and even clipped me through the ceiling into the armour beetle strolling around above (which could be sick tech to get red key early if it didn't like, require red key). And that's just at one burger collected, it'd probably be even jankier at higher weight stages. (this section was annoying in previous versions but now it feels broken)
