The limit is eight. When somebody freezes that means that person lost a life or died. Jump through the platforms that are pink. Watch out for spikes and lava and enemies! Wall jump up the walls to go to a scene up there. Use the arrow keys to move. Press the jump key and the left or right to wall jump. (You have to wall jump on a wall.)
Thanks to @griffpatch for the tutorial. NOTE: The enemy can go up to any height, so be careful!
