Deduce problems in your environment, find hints, and move on to the next level! Use movement controls and balloon skills to move forward.
Pong is a balloon character who can bounce around and fly for a while. PC single play is also possible, and local one-com co-op play is possible if you have a gamepad.
Explore maps with different atmospheres (Island, Sky, Desert, Countryside, etc.).
There are missions that stimulate curiosity in the game. There are quiz elements that can be solved through reasoning, and obstacle elements that can be solved by actions such as assembly and manipulation. Don't give in to difficult quizzes and tricky obstacles.
