Sling Clash Hero

After playing games like PunBall, I stumbled across this game. It’s really straightforward, aim and shoot. However, you can get coins, extra balls, etc. The coins have no purpose whatsoever. The balls are easy to get and you get so many tries and can also get more throughout the level. Instead of more levels we probably need a use for the coins. Like more skins, different sized balls, bonus levels, etc. just no added ads that makes the game unbearable.
