Ultra Mortem

"Well, it looks like you've died. Before you can enter the afterlife, you must complete a challenge. There are three things you must collect, though not in a normal sense. Unlike how things were in the land of the living, you must seek out things to kill you again. This test is prevent souls from becoming ghosts. Instead of being stuck in the living world, haunting innocents, you're here until you accept your death.

To move on, you need to do the following:

1.  Find a creature to kill you (check near the beginning) to overcome your fear of being eaten. Do this, and I'll give you the speed you didn't have in life.
2. Find spikes to jump on (try and find a hidden area under a platform). Do this, and I'll hold you aloft for longer, letting you jump farther.
   
3. Find the edge of the world (you may need to find the spikes and creature first) Do this, and I'll give you an extra jump.

Once you reach the flag, your journey has come to an end.
