Overall, your game was pretty bloody fantastic. Platforming felt good (though a bit floaty), and visually it looked pretty spectacular.
I have two gripes: one, your story didn't grab me. I read a few of the dialogue lines at the start, but when the text for me to read was larger than the screen itself, I phased out and just walked past it, it wasn't worth the effort of reading it.
Two: in the falling section with the spikes, there were times where I couldn't see which platform beneath me I was supposed to jump to next - I was on the lowest platform that didn't have spikes on it, and I couldn't see any way downward. I'd recommend either making the screen taller for this section, or positioning the camera below the player during this part.
Overall, once again, game's flipping fantastic. Smooth as butter.
