Where would you have liked more information regarding the controls and mechanics specifically? In a nutshell, there's only two controls: Turn Left or Turn Right, that'd be the Left and Right Mouse buttons for most players I reckon, but arrow keys or A & D work just as well. There's some progression information in the UI at the top regarding how much food you've eaten and how many powerups you've grabbed and when the next Warp is, but it doesn't really need to be paid attention to. Just keep eating food and dodging trouble; The Story of Life :)
