I like the art and atmosphere of the game.
I didn't understand at first what the goal of the game was. Maybe adding something in-game to give you an objective.
As others said, it needs some balancing because there are a lot of monsters sometimes.
Maybe if you're in darkness Monsters stop running towards you, or leaving you alone so you get a tradeoff between moving in darkness vs dealing with monsters.
but all in all cool concept.
Good job submitting!
