I don't know if you can do reverb in Garageband, but it would have probably sounded cool with reverb. Get this: There was a song on Monstercat called Edge of the World, and IslandJump1 and I made a song called Edge of the Universe. So world turned into universe. Twice. Isn't that something! Yes, I would call the song video game music, probably not chipstep because the song is pretty low key and calm.
