Daaaaamn, that's the creepiest atmosphere I've seen in a game so far ! The art and audio are really on point, bonus points for the heartbeat =p !
The concept is good, but I don't know if I was unlucky with the RNG, but it was really hard to keep track of the maze evolution and I just ended up using the basic strat of "always following the same wall". Maybe something like showing the path of your previous run could help greatly to have a better idea of the layout ?
I did 3 runs, found a mirror that spawned a ghost in my second run and a dog in my third, but couldn't get out, so I don't know what it did ^^'.
Also... I don't understand everything, but... "Strange children, they never forget to forgive me, [???] command, I wonder, I wonder", what is that xD ?
Overall, a nice game, GREAT ambiance, but it needs just a bit of polish gameplay-wise for the maze to be even more interesting and fun to go through ^^.
