Very nice idea, graphically nice and well done in the programming part.
The thing that I perhaps liked least was the level design, in some points I got stuck without the possibility of dying to make it easier to get back up.
The dying mechanic to make that area "walkable" is truly brilliant!
In the game I made I brought a similar idea, but being a platformer I had to think of something different.
Consistent with the theme and the special object, I am pleasantly surprised.
