This feels off-topic now, but I started playing Hotline Miami again. I stopped a few months back when I got to the 4th chapter or so. I finally pushed through and now I'm at 14 (2 left). The boss fights in this game are ridiculous.My only big critique is that when I succeed it often feels like luck. Enemies just happen to miss me or take a weird path. Still a fun, frustrating and eventually rewarding game.It took me 30 or so tries to beat the guy with the knife and the dudes in the van. But a "try" takes anywhere from 5 seconds to a minute, so it wasn't too painful.
I like that the game plays around with the mechanics later on and asks questions for the player to think about (what exactly is real?).
My strategy for that guy was
use his own weapon against him. Round up the fodder enemies and lead em through the fire.
Glad you're liking it, it's my personal GOTY 2012.
