Thankss!! This engine is really cool, you should try it someday, the development process isn’t that boring. And about checking for impossible levels, I do that manually, I play and see if it’s possible to reach the platform. When it’s too veryy hard or impossible, I adjust the character’s jump height until it works. To be honest, I’m not sure if there’s an easier way to test this, but I’ll look into it.
