Could someone tell me how Cocos Creator compares to SpriteBuilder? I'm very new to game development, and I was using a Make School tutorial on how to build a Flappy Bird clone with SpriteBuilder and Cocos2d/Swift to try to get a feel for it. But then I realized that SpriteBuilder seems to be dead (no updates in forever, and is not in the App Store anymore), so I don't want to continue down that road if it's a dead end. Creator looks like it might be the same kind of thing, but I can't find any information (other than the sparse bit on this site).
Also, if Creator is a SpriteBuilder replacement/improvement, are there any similar tutorials that teach how to use it while making a game, like the Make School one? I saw the links to the sample games, and one of them is a Flappy Bird clone, but I don't see any materials to go with it. I tried just downloading it and opening it in Creator, but when I try to run it, it opens a browser window that says there isn't anything in the scene and asks me to add something.
