I'm honestly in love with the tone and style. Almost felt like early skater vibes, but with kind of a creepy, NIN undertone to them. I could see it going either way.
As far as the gameplay mechanics, I like the idea of connecting nodes to bring them to specific values, but I was expecting more to be layered on such as these symbols multiple, these divide, etc so you could move between nodes to get the numbers you need or something along those lines. I recommend that you play some puzzles games like SpaceChem for inspiration on what you can do with simple look puzzles that turn complex quickly.
Honestly this feels like the start of a game where you layer more of these mechanics, and add in a subtle story throughout it that's either chill or creepy. Haha. Like I said, I could see it going either way with the vibes of it.
