It's been around for a while now, over a million downloads in the world and it used to be more expensive (the price dropped for Halloween).
It features only league of legends characters and their moveset. The game is satisfying all right, but those people are making huge money over copyrights if i'm not mistaking.
Riot should really do something about it. I know i would be totally pissed off if some junkies took my projets and made money out of it;
