I got this when it came out and trying to play through this has pretty much become an annual tradition, i usually get through one or two missions before becoming frustrated and quitting. But this was the last time, if it takes you seven years to get half-way through a 6 hour game then clearly you aren't enjoying it.

It's just not fun and i don't think the one-hit kill style works here. In something like Hotline Miami it works because of how fast and frenetic it is and how relatively short the levels are, in this levels can take 5 minutes and the pacing is slow which makes it insanely frustrating when you fuck up and die because an enemy hid in the shadows or took one more round than usual and you ran out of ammo. A checkpoint per level would have made it more tolerable.
