While the action does not stop until you die, the Cubefield feels very much like it has levels for a number of reasons. The first is that every so often you are drawn into a tunnel-like system from which you cannot escape. Emerging from the tunnel gives the impression of a brand new level. The second is that after a while the game changes colour scheme and style.
You use only your keyboard in this game [WASD] or [KEYS] for movement.
Try avoiding objects as you can
