What happens when you combine Hotline Miami with Superhot? SUPERHOTline Miami, obviously. As the name implies, the browser game combines the reflex-driven topdown shooting of Hotline Miami with the movement hook of Superhot. That is, enemy bullets only move when the player does.
I only played until the second level (I was starting to receive resentful glances from my co-workers) but it's pretty fun, despite the barebones presentation. It's the work of indie developer Florian Dufour, who knocked it out one evening when he was bored (he's currently working on a game called Fast Travel: A Speedrun Journey).
