Always remain positive and optimistic, that's the best way to deal with hectic schedules. Now onto the subject of Dimention Spark: To be honest, have you considered using a "fluid canon" for the plotline and characters? If you have trouble with set plotlines or events then why not try to make the flow fluid so that it could possibley flow multiple ways. Simply get yourself a sketch pad, draw an' map out your characters and ideas and then "fill in the gaps" to interconect and tie them all together. Also don't fret too much on production troubles, the creator of Dust: An Elysium Tail spent around seven or so years trying to make the game with little outside help.

Then again, what you could do is create an "alternate what-if" narrative if you feel you can't do the narrative that you originally wanted to do. Just use as many set elements as you can and then try to work from there. You could also try writing it out in a short-story format and then work from there to adapt it into a game....

Ah, thanks for the advice, Larka.
