Tried it again: Not sure how i could miss the shotgun. Feels way better than the SMG. Makes sense to have the latter as a backup only then. Couldn't find the rocket launcher though. Jumped across some vehicles, roofs and ledges, but nothing :(
This time i also tried to die. One thought about that would be to show the "You are dead" thing automatically after a few seconds. I think the player understands that hes dead because the HP hit 0, but just laying there, the screen not fading to black and nothing popping up until you click feels a bit off.
To add a bit of praise after leaving more critique: The heads of robots/saw dudes are a really cool idea. Just saw the switch from "Search" to "Attack" on the melee dudes when i let them kill me. Its a subtle thing that pops more on the walking monitor enemies, but it adds to the experience.
