I just got through Hotline Miami.
That game isn't suitable for, like, anyone. It's a murder-sim straight out of the 80's: huge chunky sprites, lots of screen tearing, everything executed in garish shades of neon.
But the melee combat, oh now that is the thing; it's all in the timing and the distance, but one hit kills (Either you or your opponent, depending on who gets the hit). It's about rapid-fire knife duels, darting in for that quick kill, dashing around corners and hoping there isn't a shotgunner watching over your target. It's about picking your fights, playing smart, and always being in the right place at the right time. It's about planning the next two seconds of bloody violence and then executing it, flawlessly. It's about constant restarts as you learn the best angle to attack the room with a shotgunner, rifleman and two dudes with clubs.
It's a horrible, violent, high-speed mess and you should play it because it's wonderful.
