i've been playing this game for a bit, and it's super fun so far! i think the only things that need a bit more work are trash items, as there's just a billion of them and you can only move three with the starter belt. so maybe a VOTV-like trash pile system? you shove the items together and they form into a bigger clump of trash, up to a max size (which would instantly make a trash box when recycled). also, sellpoints. they are really tiny, and it's somewhat difficult to actually put a trash box inside them. maybe make them larger, or make them a bowl instead of a flat plate?
The wobble when moving is also really exaggerated, and makes the fine movements for lining up objects annoying. Maybe make it wobble more the longer you've been moving? that way you're disoriented from running a while, but not when just shifting half a unit over.
aaaand there's a bug. for some reason, after saving the game and reloading within the save, all of my items in my backpack and belt, my heart rate, and probably all of my other stats were reset. it might be fixed by reloading from outside the save, but i didn't test that.
Edit: It looks like part of the bug is that, if an item clips out of bounds (such as through a thin wall), it teleports to the very center of the first room. The disappearing items look to be visual, but i'm just not sure.
