A simple guide to making a maze game which relies upon several key scratch ideas such as broadcast and sensing of color intercations. The game is incomplete and is ripe for extending.
After teaching students some basics (stage, sprites, costumes, loops, movement, ask/answer, broadcast/receive, variables), I challenged them to create their own projects.
"May I read your mind?" We play a binary guessing game and read their minds. After explaining the game, we program it in Scratch, starting from a project that only requires a few key additions.
