Primary 7 have been making games on coding software called Scratch. They had to also market their games by posters and also write instructions. Some people edited existing games and changed the character, backdrop, etc. Others made their own game from scratch, on Scratch!
Flappy Cheep Cheep (like Flappy Bird)
Cat Splat (avoiding dogs)
Shark Mania (like Super Mario)
Hungry Space Unicorn (eat as many things as possible)
Flappy Christmas (like Flappy Bird)
and many more!
