Nah, it doesn't even track which direction you're looking. Looking straight ahead, walk into some sugar cane so your whole screen is green. Now look up. It thinks you were looking down.
I guess it comes down to your definition of state. I'm not saying there's enough state for this to be playable, but there is clearly state and I think it's important to point out how impressive the amount of temporal consistence and coherence this model is capable of, considering not long ago the state of the art here rapidly decohered into completely noisy pixels.
I guess if you consider knowing what color the pixels were in the last frame "state". That's not a definition anyone would use though. Spinning around and have the world continuously regenerate or looking at the sky and back down regenerating randomly is the opposite of state. It's complete incoherence.
Just a thought - complete incoherence is a noise function, no? Successive frames here are far more correlated than that, which is pretty remarkable.
My definition of state is something like reified bits of information, for which previous frames and such certainly count (knowing the current frame tells you a lot of information about the next frame vs not knowing the current frame).
