Hello!
I liked the concept of the game and the ambience was quite good. Also, you managed to implement all the bonus challenges, which is really nice. I had some trouble with the ghosts in the maze and died many times, but I finally managed to find an exit and completed the game. My main issues would probably be the size of the sprites (I'd recommend increasing their size by 200%) and how difficult it is to navigate through the maze if you don't get the lamp from the old man at the beginning. But overall, I believe this has potential and the main theme was implemented properly.
Good job!
