Somewhere between the Universes 4 worlds are being created over and over. And the balance should be kept. Each of four worlds has it's own pair - Fire-Water, Earth-Air. Collide worlds and keep the balance of the Universes. It can't handle more than 30 worlds - otherwise it will fall apart.
The Universes has two cycles of life:
- Fire-Water cycle when the Fire and the Water worlds are gaining momentum and it's not possible to collide them. Only the Earth and the Air worlds are collidable at that cycle
- Earth-Air cycle gives a full strength to the respective worlds and it's possible to collide only the Fire and the Water worlds.

Cycles replace each other, be prepared!

There are random fluctuations in the Universes and very rare unique Iron and Ice worlds appears. You should guide them to the ground and sink in the Fire and the Water respectively.

Controls:
Mouse only. Drag and guide a world to it's pair to collide them together. Special type worlds should be guided to the ground of a respective type.
