I really like the art style, and the audio fits well, which really amps up the scary vibe. A few minor downsides: it's sometimes hard to navigate the dungeon, so you end up walking in circles (well, I got lost for a bit, at least). The scientist AI is a bit slow, so you're constantly waiting on them. Also, it's not super clear what to do at the star, I would've liked a quick in-game tutorial.
Overall though, great work! :D
