Use your mouse pointer as your flashlight. Look around for the hidden keys and click to collect them. Beware of the danger that lurks in the dark. Click the monster before he reaches you. True Arrows will point to the keys. Beware of the Deceptive Arrows.
This was inspired by a cool flashlight gimmick I found a long time ago on Featured. Since then, I have always wondered how I could use it to make an actual game. So eventually I came up with this. I think it's pretty nice.
