A lot of great stuff here, especially the voice acting and world building.
The actual gameplay was pretty simple, I didn’t really feel like I had to make any interesting choices, just run around and either avoid/kill the enemies or collect samples. It might have been nice if there were clearly consequences to those action (e.g. collecting a sample taking longer and therefore exposing you to attack).
The ending added a nice layer of interesting to story, though.
Nice job!
