The music? Fantastic. It heightens the experience so much. Even the ambient sound effects that were added are amazing! I love that everything makes a sound, even if it doesn't have an interaction. For example, the bed makes a spring noise when interacted with, even though there's no dialogue etc. It is a subtle touch, but means so much in the grand scheme of things.
The visuals are fantastic. The cut scenes? Astounding. This game is such a treat for the eyes, and the visuals go way above and beyond. I loved watching all the animations, and once again, they elevate this game to a whole extra level.
The symbolism is amazing in so many areas as well. The doll, mother "changing', Tom's appearance, etc. You can infer so much through these tiny details and I love it so much.
I play a lot of these games, and this one felt very polished-- especially for a demo. I didn't dig too hard or stress test anything, as I played just for enjoyment. I didn't run into any immediate issues though, which is more than I can say for some other demos I have played! Like another said, I think the name being at the top of the textbox would be a little better, but that's a really small thing.
Overall this is fantastic, and I can't wait to see what we get at full release!
