Cool game! I unfortunately couldn’t finish it. I got to floor 3 and unlocked gate 58, but the game was just too hard. I thought I was at the last gate (gate M or something), but then there was another (gate A8), and I just kind of lost my patience trying to figure out where gate A8 was.
However, I did like the atmosphere, and the voice acting was really well done. I also liked the concept for the gameplay, but it was really hard to control by looking through the camera. Maybe using the camera to try and find a light switch for the floor and then parkouring in the first-person view would play much better.
Great game! This was really good for two weeks worth of work!
