Hey, there's a developer called voodoo.io out there who keeps ripping off of indie devs' core game concepts, and releasing a shitty F2P version on app stores before the indie devs have finished their games.
Goldman Sachs gave them $200m in investment recently, so they're not going anywhere soon, but you can encourage you and your friends to ignore the fuck out of their games.
