Hey there! You're the second one who suggested that and we're working on it for the 0.0.4 version of the game. It's kind of a sandboxie game so we're still figuring out what it really means if you "did everything" in a version (Not everything is needed to progress the main story like with Nova).
And about the story, this doesn't really follow the normal winx story line. Some parts are still in it but some parts aren't. And even as a student, you don't have to always have to follow your classes ;) You can indeed see it as an alternative universe.
Andd correct! you'll see them more often eventually. We're still in the early stages of the game.
Thanks for the rating btw! We really appreciate it :D The public release of the 0.0.3 version will be released on the 11th of october.
