ok not sure of the game name but I can describe it pretty well.
it is a little two wheel rolling box going up,down,forward,reverse can spin etc. going on thin planks & moving platforms.
If you make it through the level screen room a little doorway takes you to the next.
If you don't make it then you Fall off that seems to be to the center of nowhere. it looks just like this robot Rollie
