Some really cool visual stuff, and some great ideas there, i especially like the light spear, i think that was very creatively implemented. I liked the effect before it tells you how to use the light spear. The sound design was good. Some clunky jumps here and there where the player's size relative to the world makes it awkward make it a bit awkward, and the character being black on a black background makes positioning for some jumps a tad difficult, i am not sure if there is coyote time of some sort implemented it is hard to tell, perhaps that could make the jumps less clunky, and sometimes, its hard to tell which way the player is facing but that last point is nitpicky.
All in all a great submission that i enjoyed playing through, and it had some really interesting ideas.
