The purpose of this game is to during the most time that is possible and improve your score to become the leader of the leaderboards. You can earn money in the game or watching ads and they serve to buy upgrades or some characters. I also add the possibility to create a league to play with friends

you need to click on that ball? (didn't install it yet, I'm asking because the screenshots don't reveal much)

 

[SSDM71]

yes, you have to touch the ball to move that, I attached two other screenshot
