Really nice, tough as nails though :P Turning down the difficulty a bit would've made this a lot more enjoyable, because even the first level made me pull a couple of hairs. Adding some I-frames at the end of the dash also would've helped. Last thing I didn't like: why do I have to start over again if I die? I just want to play the game man :c
But still, ignoring the difficulty, awesome visuals, nice music choice, and snappy movement. Really good job overall :)
