That was a truly delightful and creative game. Really loved seeing some of the ideas for the monsters. Great work!
But I found a glitch! I don't know how exactly, but when I returned to the room with the torch (where you wake up the monster with the loud flute) there was no way out; I was stuck and had to restart the game. This happened after I both 1) woke up the monster and got the torch, and 2) moved the boulder and talked to the monster at the end of the path. I'm assuming doing both these things will make the torch-room broken.
Other than that, it was a really fun game.
