Really neat concept! I think you could take this and run with it and make into a fully fledged experience. Really nice art. Here is some of my feedback:

1. Don't start the player with the light on. My first impression (meaning the first opportunity I have to look at the screen and interpret all of the information presented to me) was simply me watching myself lose at the game. I took too long to observe everything and ran out of light and died.
2. Monsters seemed to not spawn frequently after wandering into the woods for a while.
3. Adding audible cues to the monsters would be a great way to improve the experience so that you know when they are coming.
