Really impressed with just how much explorable area there is in this one! Given the time constraints and the various other considerations of making a game like this the level design stands out for being well thought out and expansive. The tight corners and dark spaces gave me some tense moments and the audio of the 'ranged enemies' also made me jump a number of times.
The vending machines were a really nice touch. I felt there was a good balance of materials (ammo and health-kits) spread throughout the map. I liked the general aesthetic, the differently coloured lights and brutal concrete.
It was nice to have a couple of guns to choose from, though I felt the pistol was almost good enough on it's own. Would have been cool to get something quite different near the end section, but this may have gone against the overall tone - so maybe not.
Nice work :)
