Visually, this is fantastic, I love the layout and the atmosphere/design is gorgeous, those little spider webs are adorable. For a first indie horror, this is amazing. I think the one thing missing is the story part. With a bit more background info on the painting/the house, this could have been perfect, but without it, you somehow miss what would be so scary/tragic about the painting (and I read the story afterwards, it's a great story for a short indie game).
However, please continue because with a first game like this, I can’t wait to see what you come up with next. It's a follow from me!
