The premise, the art, the inspiration it took its "ideas" from and so one are questionable at best so lets not waste any breath on this.... "demo" i guess.
That being said "Fairy Tale Adventure" started as a snow white trainer game just like this one. And after that it got more and more original until it was an completely new game.
And even tho it wasted all its potential and turned into some horrible generic bs (mostly bc of writing but I'm going Off Topic here...) it evolved somehow.
What i'm trying to say: there is a tiny chance this is the same situation here. This demo could lead into something completely different than what we see right here. If that happens it still has a small chance ( ' -')
tldr: erase everything so far. create a new game.
