I’m all signed up to be a BSA merit badge counselor, and tomorrow I will have a couple of classes where I will be teaching boy scouts how to make some games with Scratch!
I’ve posted my instructions & Scratch tutorial here on my website:
I bought the Merit Badge Pamphlet for Game Design from the local boy scout office, and let me tell you – I did not expect it to be so good. Whether or not you’re a boy scout (I’m not, hah!) if you’re interested in game development you might try to pick it up. It doesn’t have specific lessons with any given tool, but it goes into a lot about design and methods.
I’m also now hopelessly addicted to Scratch, because it’s just so easy to use. I’ll probably waste bits of free time here and there making arcade-esque games.
