There are already circles in Minecraft like the Enderpearl or the Endereye, the Compass or the Clock. So why no round moon? It is not completely round of course. It will look a bit like an Enderpearl with that pixely circle. Believe it or not spheres and circles are already a big thing in Minecraft. Just look on all the buildings. There are not that much buildings completely without cirles and spheres. So please dont vote "sqare" just because of that 'round thing in a blocky world' it will fit in. I dont wanna force you to vote "round" but just vote whisely.
