This has a solid style with some fine flow at times; I like the lighting a lot!
The only nitpick that I could offer is an odd bug in which the S and A keys combined in function. I could not go down or left, but could go down-left when pressing only the A key; yet, the S key would do nothing.
Refreshing the game page fixed this in a jiffy; however, I could not recreate the bug. Just some (hopefully) useful info for future reference! Great work nonetheless.
