I agree that it has some different gameplay mechanics -- the teleporting, and having primarily melee combat. But, to me, it still feels like Hotline Miami was their primary inspiration.
That said, I am enjoying it quite a bit, probably about 80% of the way through. However, I just wish the hired a better writer (the dialog is cringe worthy), hired some voice actors, and spent more time polishing it (difficulty spikes, crashes to desktop, etc.)
