Just finished playing through it for the second time today. Deffo gonna be going for a third before too long.
At first I hated the re-spawning enemies. I like chucking grenades like billy-o to clear rooms and that doesn't work so well in certain places in this game, although it does at times unless the sneaky spods chuck 'em right back at ya.
Once I'd gotten the hang of the new style of game it's easy enough to come up with new styles of play. Blasting peeps in the face with the shotgun for example, ooh that's a fave technique at the moment.
The only thing more satisfying is when an enemy tries standing up again after being shot and you have just enough time to stick your knife in them as they're staggering about. Good times.
Yeh it's short but surely you agree that a great, short game is a lot better than a long, turd game
EDIT:: I would quite like the chance to choose what weapons to start the levels with, if only so I could exchange the pistol for a shotgun.
Maybe with recommendations so you didn't go into a fight with something stupidly inappropriate (unless you wanted to). I've gotta admit though, quickly switching to the pistol instead of waiting for a reload is a technique I never really used much until I played this.
Blammo in your face!!
