Go inside the project, add yourself dancing along to the music, and then remix! I've made a base sprite already to help, so all that you need to do is a bit of artwork. If this is any kind of successful, I'll make more projects like these in the future.
Mainly did this as a sprite test, but the fact that the 'add yourself' has thrived since my joining of the website warms my heart a little. (- Retro) P.S.: While slow, GRAPEQUEST: Remastered is going mostly well. Have like half the OST done, too, which is a nice bonus. Still need to figure out a better title.
