This game has boat loads of potential and would have been an easy 5 if not for a few problems.
I really liked the graphics. You did a fantastic job of pulling off a minimalistic approach. I liked that you included a full screen option; more people should do that. The music/sound was great and did a good job of setting the mood.
I appreciate that you make wasd controls an option, but they didn't work.
I think this game would benefit greatly from a little more polish in its design. These are the changes I'd personally make:
The 'Start' and 'About' buttons on the main menu seem to stand out like a sore thumb using a plain font. I'd use the same font you used for the title.
You should explain what your goal is and that the ghouls kill you. I didn't realise that until they killed me the first time.
I also think a map would really improve the game play. I found myself wandering helplessly with two lamps left.
When you die, it's a real drag to have to start from square one. After the second time I died I didn't care enough to try again.
I think some tweaking of the paths you follow is needed. Too many times I was being chased by a ghoul and was stuck battling what felt like pixel-perfect jumps. It really detracted from being immersed in the game.
Overall this game has a lot of potential, with some minor fixes it'd be a great game.
