Interesting idea with different rooms!
I didn't immediately understand what to do, though, so I tried to open all the doors I came across... Hah... But then I was able to find the key!
However, I had a bug: when I went straight to room 110, I just fell down through the textures. After the restart of the game, this bug was no longer.
But if you don't count these few shortcomings, it's a good game! I really liked the scene with the torches fading. It was scary heh
