Do we know who made sburb? It's been around for some unknowable and paradoxical amount of time because its use creates universes but I was just wondering if there was a creation of it or anything

It was made by different people in each session but all of them are based on a technology found in the frog temple which is paradoxically created by the game and sent to the planet so that the game can be made.  So I guess technically the game makes itself?
