[nightmare_of _death]

I recently got this game,played through it pretty fast.(normal mode) but now I'm at the last section of the game.and I can't go back to get more health or film.I have no film left accept the crappy stuff. (I used everything else to beat a ghost(really difficult)...and my health meter is really low.
The tunnel before I have to beat the final boss is full of enemies. I did come across a little bit of heath,but that doesn't last long.I think my only strategy would be is to run like hell and just hope I hae enough supplies and health when I reach the end.

I'm thinking of starting over, and trying to save my resources more,but I also want to complete the game now 'cause I get to open up some pretty cool stuff.
