Very fun ! The concept is very good yeah, i think the obscurity it's just a biit too obscure but well, is not really a problem. however, there's a little confusion with what happens sometimes, I think you should add a little light for the monsters, and a big light in the endlevel zone...but the gamedesign is good, the fear bar, the darkness,...do a strong feeling of opression :D, and,so, when you are in a light spot, is soo satisfying because of the contrast,haha !
