Hello, I enjoyed playing your game. Thank you for sharing it with everyone here. I am a fan of the music you added when the ghost appears, but I think if there was a quieter , alternate music track that plays while you are searching for artifacts may improve the game.
The fact that the maze always changes with each play through is very cool.
All in all, it is a bit repetitive since the ghost always appears when you pick up the last artifact, but if there was some variability in that matter, I think it would be even better.
