Gravitas!

In this fast paced puzzle-shooter mash-up, you are the captain of the defense force of Gravitas, a peaceful galaxy far away from Earth. One day a wormhole appears in the center of Gravitas and begins raining debris and trash into the atmosphere of the galaxy’s various planets. To defend against the invasion, you must match three or more of the same types of trash and launch them back into the wormhole. Hit the wormhole with enough debris to save each planet. Complete all 20 levels to eventually uncover the source of the wormhole and shut it down.
