A space that feels as if the world has been turned inside out.

Make the city come to life by placing giant building blocks of houses and stations, running various vehicles such as cars and trains, and developing transport systems.

When blocks of the same kind are placed nearby, they are connected to let the vehicles move along the routes created. Connect the blocks, and the vehicles will evolve more and more. Helicopters fly from the building and the world seen from the helicopter is projected on the screen in the sky.

The world has a river running through it. When it rains, the river floods and the water runs into the city. However, building a waterway with pond blocks and connecting the waterway to the sea will prevent flooding.
