Really cool rendering! I'll admit my lack of patience made it so I never actually got to the first enemy -- was close, but the game ended as I approached. Platforming was pretty tough due to both the camera and how fast the character falls. I think with a slower falling rate, it'd be a bit easier to get used to. Character rendering looks interesting and as if done by a shader or something as well.
Isometric felt a little claustrophobic, but that might also be because of the darkness.
Very neat graphics rendering! I am envious of your ability to do such interesting things with shaders. :)
