212 route: The key is to push the block onto the red keys to deflect the fireballs onto the trap buttons. Start at the top key and work clockwise. After pushing the block onto the last key, collect the chips to the left, then the chips to the right (the last key is not needed), then go through the traps and press the green button. Clone blocks to reach the chips in the top left of this room, then get the chip in the bottom left, then the top right, then the bottom right. Open the red door, and push a block through into the water 2 spaces below the rightmost chip. Clone another block, and push it along the fireball row, stopping to collect the chips, then exit.
