I really enjoyed the atmosphere and the strong old-school shooter vibe—it gave me some Quake-like nostalgia in a good way. The ambient sound design does a great job pulling you into the experience, and small touches like the door and interaction mechanics feel satisfying.
That said, I felt like the gameplay could go a bit deeper. Enemies seemed a little too passive at times, and I think adding some more challenge or variety—maybe through AI behavior or additional mechanics—could make it even more engaging. I also liked the idea behind powering doors with the gun, it feels like something that could be expanded further.
Overall, this is a solid and enjoyable jam entry with a lot of potential. Nice work!
