The top number is how many lives you have, the bottom is room number. Edges and light blue areas are the 'goal' that will progress you to the next level or the end. The orange follows your mouse. Don't let the orange die. It can't go past black, and will die if it touches the blue spikes. The juicer that chases you can pass through black, BUT will die from blue spikes. The key unlocks doors, and the button turns on a spike that kills the juicer. don't get juiced.
Sorry, third level is glitchy ------------------------- for school ooo weee got the pictures off of the internet
