Music becomes repetitive in a matter of seconds, I'm not gonna lie.
As for graphics they are fine, it has a camera that follows the character, screen shake, particle effects, although the graphics of the level maps are always the same, something like a recoloring of the graphics between levels would have helped
In gameplay it feels limited that the only thing you can do is move and jump, something like a weapon or powers would have helped.
Also you need to put a message that says "press ENTER to continue..." in the backstory. I spent a few minutes figuring out which button to press, since in the readme.txt file it just says to use A, W, D and F as controls
Score: 6/10
