Very well done
A refreshing new style;
Try adding some upbeat music, not too loud, but something like a suttle undertonetune. It will make you bop your head more and go"yeah scream baby!"
Sort the controls out a bit more. e.g. i use the arrow keys and with that I automatically thought that jump was space bar (all NG games ave this format) so i kept screaming when i wanted to jump. A minor technicality but something for you to think about.
Cool ending!
