|Difficulty: Above medium|
This is the second-last level of the M-tunnel.
This level shouldn't be able to overwhelm you if you pay much attention to the crumbling tiles and the gap in front of you. Use long high jump to avoid the holes.
Tips: If you find yourself falling out of the tunnel and there are also some crumbling tiles falling under you, try jump on them, and this may get you to jump back into the tunnel.
