This looked really polished. I thought the first puzzle was really satisfying, had to spend some time figuring it out. But then I got stuck in the elevator. Every time I entered the code, the code at the top would change. Kept entering them but nothing happened. Maybe I missed something.
I thought the mouse turning speed was a little too high. I'm usually complaining about it being too slow, but in this case it made it harder for me to select the buttons to enter the codes.
