To move just click right arrow to go right, and left arrow to go left. (If you need to know how much they go 90 degrees) Lengths means how much points you have rainbow food = 2 points and normal food= 1 point. Score is basically a timer every 5 seconds the characters speed increases. Pet added at 60 seconds (a minute) you will get a pet that gives you 3 length per second!
I will be trying to update frequently, the speed increase only goes up to 45 currently! If any bugs tell me. SPOILERS:The next update will be a global leader board.
