This deal blows, let's suck stuff up with black holes

Head on over to where you get to play as one of many competing black holes that eat the world. Black holes live a simple life: the more you eat, bigger you get. The bigger you get, the bigger the stuff you can eat (including fellow black holes).

Let’s play Hol-io!

Also someone please explain to me why all the games these days are called “-io” even if they don’t use a .io domain…
