Interesting game idea.
It sure give an eerie feeling walking along those corridors. Sound and music fits the game well. The hunger and sanity is a good mechanics, but the yellow color of the hunger makes it hard to read. I died several times due to not seeing this meter. There is a hunger sound, but it is easy to miss.
The spelling to remove the ghost was neat, at least to begin with. After a while if felt like a random encounter punishment which I could not fathom why I received, what did I do wrong. I would have liked to have a meter for the gas in the lighter. I got lost in the maze all the time and just backtracking to find my way ended me up in even more encounters, hmm.
I liked the graphics and general feeling in the game, Good Job!
