Scratch 3.0
Scratch is pretty great, and at least 3 of my kids constantly ask if they can play Scratch. Unfortunately, for 2 of them it usually means just putting characters on a stage and adding code to change their costumes when you click the green button.But if you have kids who want to step up their game from Scratch, check out PICO-8 (submitted it earlier today, check my history). It's genuinely amazing, and my oldest absolutely loves using it. He's made some awesome 2d games so far over winter break and he's using legitimate programming concepts and techniques like they're nothing, it's really amazing to watch.
