Your game had a really mysterious touch, good job. I really liked the art and music, though you still should improve them, i really could see how much effort you put in the game.
But sometimes the movement and sight was a bit tricky by some walls, you really should look how other games like yours handle wall collision, player sight etc.
And maybe you make the levels at the begin smaller, maybe first with only one enemie and more explanation about the strange grandfather.
This is my game, would be nice to get some feedback
