[Review] Ball Sorting Puzzle Game

I picked an easy game because KakaoPage gives you cash for playing games. I quickly installed it because the game event during Chuseok gave double the cash. Now, the double event has ended. This game is about putting balls of the same color into empty containers to finish. It's simple yet difficult. It's easy at first, but gets harder as you progress. I've reached level 35 so far. My next goal is to reach level 50.
