I late more than one year using Scratch to learn making a platformer. While that, I learnt to doing easier things, like mazes and interactive stories. That's just a tip, ok? There's a Scratch Extension called "Blocklive Scratch", and that is used for 2 or more people make a collab, understand? Doing the same game. I have this extension. You can install that to we make a project, where I can teach you some easier things. Remember: Easier doesn't means worst.
