Squareworld is possessed by spirits and is slowly sinking into oblivion.

The only chance for salvation is to banish the spirits, starting from the bottom all the way to the top. We will do this by summoning glass squares. At each level, it is necessary to hold at least 50% of the field. Click with the mouse or touch the screen and it will start summoning at that location. The glass square will be complete when it touches the edge of the screen or another square. Avoid the square coming into contact with the spirit while being summoned.
