I'm not sure what to advise on Hotline Miami. I've gotten relatively deep I think; but I know I'm missing out on some functionality. For example, i can't seem to learn how to switch masks; but I suspect that comes later in the game or on second playthroughs.

Overall, being fast to hit someone and finish them at the same time is VERY handy and a quiet takedown as a melee attack. But, I tend to stealth kill to a point, then wake the guys up with range weaponsa nd either assault or get them inot a bottleneck and get multiples of them quickly. Also, earlier on there was a stage with a trapped door. You can shoot those to take care of business. So, there is obviously some minor puzzle elements to the game as well.
