Earth Dome Defense

The task of protecting planet Earth has come under your control. Keep your finger on the screen to turn on the energy dome that destroys comets. But don't forget that the dome is not eternal and has a charge level! Once the charge level runs out, you will no longer be able to protect the Earth. So use the charge wisely until the end of the level. Once you move to the next level, your charge level will be restored. Don't let the meteorites destroy the Earth!
