Well, the roadmap looks solid enough to me.
Also, perhaps the reason why Mofu is not able to finish what he planned is because real life problem gets in his way? Especially this is a creative works. Its progression is prone to the emotion and the mood of its creator. I more or less know how it feels, since I do drawing sometimes, and it's hard to get it done when suddenly your mood is wrecked by an unwanted real life problem that comes out from nowhere.
At least that's my guess.
