RISE (0-3)

Also a minor one, but at the pipe checkpoint where the locked gate requiring a key is, if the player goes south and jumps behind the waterfall, they can land on and walk along the pipes below, despite them not serving any gameplay purpose.

The lava pit where the king is can be reached if the player presses against the wall while falling down, and it doesn't kill them, so they can walk along the lava, and can't escape without rewinding. The lava needs to kills players upon contact.
