I wanted to find a small game that can practice memory. I tried a lot of games, and almost all of them needed to connect to the Internet, display advertisements, and apply for permissions involving personal privacy.
So I designed and produced this little game using his son's hand-made works and beginner piano songs and other materials. It is an ad-free, stand-alone version of the green game. It does not require Internet access and does not require any mobile phone permissions.
Rules of the game: Open the same card can be eliminated, and eventually all the cards will be eliminated. The fewer the number of flips, the more stars you get, and you can get three stars to open the next level.
