This game is a teach project, is a copy of famous ballz. the project started before 3 years, when I begin to use unreal engine 4, I want to show my friends how unreal engine can do in one or two days, I finished most part of this game in two days alone.
This game have no cpp code, all code is blueprint, the game can run on PC, android and IOS. If you are a beginner and try to create a game all by blueprint, you can try read and debug this game, to know the power of UE4. if I can create this game(most part) in one or two days, then you can do it too, maybe next famous game is created by you.
