Welcome to the Platform Builder Forums yann2008yt! We love to see new faces, and it's been awhile since we had a member that was actually active. Most that join don't ever post. But I'm glad you're fairly active! I'm Christian Game Maker. I've been here for a year, and have been using PB for an even longer time. So, I'm usually the one who knows what to do because I know quite a bit about PB. I'm developing a game called, "The Adventures of Super Mike." Anyway, what do you mean by, you can't start a new file, but you can in the example? If you created all of that In the example file, it'll all get erased eventually. That stuff doesn't save. You can start in a new file by clicking on it, then clicking on new, then selecting either on simple or advanced mode. Just select simple if you don't know what to do with advanced. Advanced is just advanced linking. Not too difficult to learn, but a little advanced. Anyway, looks cool! And we'll be happy to see what you come up with in the future!
