Can't promise that I'll come back to it, though I really want to. This time around I had the excuses of limited time and lack of experience, which let me set aside my concerns. But if I come back to it later, I'd want to do the song justice. And for that, I'm gonna need to go on a whole training arc XD
If I do tweak things, it'd mostly be adding storylines for the other shades, and having them affect the mazes. And of course, exploring more of the little side-story Shiorin and Kronii have going on. Maybe different endings if you rely too much on Kronii and she overuses her powers.
