Interesting concept to be sure! Still, it needs to be fleshed out quite a bit more too.
The most frustrating bit was with the boss since he followed you at a faster pace than the ghosts and there wasn't really any clear enough way to tell when was the right time/distance to toss out one of your lovely boom-sticks. I ended up using all the sticks I got to beat him since at least half simply didn't hit him.
Also, I would have liked to see the lighter be used for something other than a glorified flamethrower, which is basically all it was used for in this case (aside from lighting the TNT of course). You could have used it at least once to open (or rather burn down) a door/obstacle or drop something on a baddie, just to give it a little more purpose within the game.
Overall though, I think this would make for a very interesting puzzle/fps fusion, and would love to see you develop it further. :)
