If players find themselves drawing a circle on the map, they can create a floating city. 

In essence, if there are no corners to build, the game will create triangular buildings. 

They have no room to support them on stilts, so they need cool propellers to keep them upright. 

Once the outline is drawn, the player can fill the space, and then go up, go up, go up! 

In order to make it more interesting, three layers were built, the bottom layer was removed, and the effect was very different from that of water. 

Multiple floating "islands" can also be connected.
