Glad to hear you enjoyed the game :)
This art style indeed feels random when you first look at it. It's an art style called 'vaporwave', where it combines 2d and 3d graphics to induce a surreal feeling into you. Adding onto the color it also feels kind of dream-like. If you like this aesthetic you can search for more online :D
Thank you for the compliment on the music too! I'm sure our composer would be very much over the moon hearing your compliment on it :)
