on 3ds, i noticed a glitch a couple of months ago: on the final rooms, concretely "tap-tap-tap", if you stand on the bottom row of spikes, in the edge of the room, and you flip while you leave it, you will get stuck between the room you were and the empty one of below. after doing that, if you go right, you will end on the V-VVVVVV room sequence, and simply flipping and going left, you can go off bounds. we all know there is a named room here, but if you flip back to the VVVVVV sequence on the edges, and you float down to the last room, in a couple of seconds you will get expelled on the other side. at this side, there are some rooms with names, but you have to be carefull because just beneath them there is a pink room who warps on all edges, so if you end on it you will get stuck.
