Wait really? That's a surprise, because the story doesn't seem to be at a point that's close to the end at all - the end of Act 1, MAYBE, but no further than that.
There's still a whole lot of plot to do with Wendy, Gab, the tyrants, the actual nature of the "game" world (beyond a quick and rough explanation from Gab that Sparkle barely understood or had time to explore), and also a bunch of growth in terms of character and relationship development AFTER the current plot stopping-point that I would've thought would still be coming - and amongst that all that the party's further adventuring.
