I like the way the game starts, reading notes in the room and figuring things out through interaction instead of being hand-held felt good. The elevator bit worked nicely as a kind of natural tutorial without spelling it out. The alien world had a strange vibe to it, especially with those green enemies stalking you around. It's simple visually, but managed to create tension once more enemies started spawning. I did like that turning in a key progress persists after death; that made it feel fair.
The flashlight functionality was a cool idea, as well. Having it reveal hidden paths and clues added a layer beyond just running from enemies. I wasn't always sure if I was using it correctly with the stun mechanic, but the concept itself is solid and definitely has potential.
Respect for doing everything yourself btw, especially running a smooth webgl 3d first person game. The game feels like a good foundation for something bigger. I can see the ideas you were going for, and for a second jam especially solo, there's a lot to build on here. Finishing and learning a ton really is the ultimate win.
