Your palette looks really good. How are you deciding the colors? Did you limited yourself to a palette? Or are you picking and choosing as you go?
Vaporwave music as well?

I'm limiting myself to a pallete. I didn't make the pallete myself, though., it was made by someone called natsukis.
I probably won't be using vaporwave music, since it tends to be relaxing and laid back, and I want the game to have a fast pace. I'll probably use something more energetic, like this song I found on Incompetech.
