217 route: Play in even step. Pick up the red key and the fire boots then move down and left, under the teeth room, to the corner. Move (4U) then right, which will move lure all 3 teeth onto their buttons. Now walk across the fire and traps and through the red door and thief. Pick up the blue key and then press the red button 3 times. Now collect the chip nearest the blue key (approaching it from the right as the teeth block the most direct route). Now lure all 3 teeth to the top row, then move underneath to collect 2 chips and force one of them onto the trap button. Lure the other 2 teeth down, and lure these teeth onto the other brown buttons in a similar way. Now open the blue door, move the block onto the red button (picking up the green key in the process). Wait  and push the block D (cloning 1 glider in the process), then clone 3 more gliders. The last glider will be sent across the traps towards the green door, where it will be trapped by the nearby force floor. Collect the flippers and follow the glider, and collect 4 chips from the force floors above. Go through the green door, collect the chips in the 2nd, 3rd and 4th columns, and push the block L 7D, then open the green door and push the block R to deflect the glider into the teleport and onto the brown button (it is also possible to push the block onto the button). Now collect the yellow key and the remaining chips in this room (the suction boots are not needed) and enter the yellow door. From the thief, move 2U (5L) 3U 3L D L U L U 3R D R and push the block up across the trap (held open by the teeth) and into the water. Now move the last block R 3U and exit the centre. The bugs will hold open the trap leading to the exit.
