If you have played maze run then the controls are the same, but this time don't touch the black lines, if you haven't played maze run ever before you press the right arrow to go right the left arrow to go left the up arrow to go up and the down arrow to go down. The way to win is you have to beat all the levels by getting to the green line, but don't touch the black or you'll restart the level.
unlike maze run in maze run 2 if you hit the edge you just restart the level instead of going back to level 1 you you go to the star of the level you were on.
