Filling: fill 66% of the level

Filling: fill 66% of the level - visually minimalistic arcade game with extremely simple gameplay. In it the user will fill the screen with the colored circles. At each level you need to make a field filled 2/3 or 66 percent. Tapping the screen activates the increase of rounds, and when you release your finger, the circle stops growing. The number of balls is limited to twenty pieces, so you need to keep within this number. Otherwise, the passage of the level will have to start over.
