Game was great from start to fiish. Loved the atmosphere; the creepy underground lab, the ominous messages, etc. They added so much more to the experience. The voice memos were really interesting as well and upped the creep factor on the creature.
If I had to suggest anything, it would be to make it so that you opened the creature's door way before you went deeper into the lab so it would be harder to get to the exit (When I played through I made it to the exit pretty fast without it getting to me), though I do believe you tried to do that with the long corridor at the sides. But yeah, an overall great short game with a lot packed into it! Good luck on your future projects!
