315 route: Move left and up, and release the bug using the lower exit (after waiting ). Uncover the blue wall leading to the block by the blue key, and return and duck out of the way of the bug, which will explode a bomb allowing the blue key to be collected. Move up and collect a chip and skates, and then collect the aforementioned blue key, and push the block U. Return, collect the green key near the start, then the red key, and exit to column 31 via the ice corner. Move around the edge of the level to the red door, open it and push the block onto the force floors, and follow it (the boost will allow the block to skip a few force floors). Move to (20,29) and push the block up as it passes, and push it to 3R D from the blue door. Open the blue door, collect the suction boots (by walking through the ice corner) and the second chip, then return through the pink ball row to collect the fire boots and push the block onto the force square. Push it down and then left towards the exit. When it is 4D from the socket, open the socket and green door, push this block across, then push the other block across to reach the exit.
