I have to admit that was really weird to just hear a song. I mean, it did have backgrounds. It's a good song. The backgrounds are nice too. I'm glad they changed. It was more like a long gif with sound.
I guess it was vaguely Sonic. I'm just really familiar with Sonic music. This sprite work is just close to those old games. You should still be proud of yourself. Anything this liked had effort put into it.
