Nice! Reminded me of spamming the flashlight in Alan Wake, haha, but it's got a real groove to it, it "feels" good to play. If I'm not mistaken the new Blair Witch game also shares this shine the flashlight concept.
Only thing I'd add is that I died at one point because one of the orbs spawned under the psyche indicator and I had no idea where to look. Beside that, nice execution! Nailed the speed of play, things get really hectic after a while.
