I was thinking on how to make the level selector for Castle Chamber, CGM gave me some ideas, and they were pretty good, but thinking I created this level selector, that is a small zone in a big hub, where you can save the game, you can enter any world, select other characters, etc. But this is only for selecting levels, actually, you can enter any world, and the worlds are unlockable, if you complete world 1, you can enter world 2, but you can't enter world 2 if you didn't complete world 1. You know?
