Over the past couple of years I have mostly worked on Super80sWorld on my own. The game was my attempt to take everything I loved about the decade and channel it into a project that encompassed all of my creative interests: music, software development, and art. Being a solo indie game developer can be hard at times - you become your own echo chamber. Every now and then, I would have the opportunity to share my ideas with friends. I would notice my productivity and general excitement increased dramatically when doing so. The game felt more "real" and the ideas flowed a hell of a lot better when I discussed the game with others.
