Play FlyUFO.io - is one of the new io games for free. Control your alien spaceship to collect objects and destroy a planet before other players can do it.
The game's goal is to consume people walking down the street, vehicles, trees, and other items to gain more control and ultimately take on larger objects such as shopping malls and apartment complexes. Since humans aren't a challenge to such a sophisticated UFO, the only rivalry is from other players - drink as many as you can until they do, and become the most powerful destroyer by the end of the 2-minute round to win!
To control the your spaceship, move it about with your cursor and attempt to hover over tiny objects to suck them up and rise incrementally. Suck up the smaller ships to avoid the larger ones. Become the supreme abductor to remind all insignificant Earthlings what they're up to.
