Really nice style and intro, I really dig the VHS/CRT visuals.
I also was a bit lost at the start, because it's hard to notice I was moving with only the enemies as reference. Maybe putting some green grid over the black background would give it a tron-esque style
I also hated the goddamn square, if you're not constantly moving it just bombs you with no warning. Could have him slide into screen as his first move, and chase from there, would be a simple solution.
