Very dark and atmospheric game. I see that artstyle is actually good but graphics look blured. It's often problem for beginners in pixel art style, so I'll give you some advise: as I can see, you are using Unity. When you import texture into Unity set the filter mode to point(no filter). The other promlem for me is lack of sound effects. During some puzzles there even no music. Otherwise, it is good for your first project. I wish you the best of luck with your progress!
