A Concept of Death

You find yourself stuck somewhere you never saw, or at least you think you did not.

In A Concept of Death, you must die in order to advance. Every time you die by something new, you can improve your abilities to further explore that place. 

When you find yourself in the afterlife,  Death awaits you and every time it may share you some knowledge before sending you back to start over.  Every single time things are different but feel the same. Would it be possible to leave this unending loop? 

The game now has just a few challenges like platforming, enemies (not moving for some strange reason) and two bosses. In order to find them, find a way to achieve all the challenges written on the right side of the screen.
