Hello again!
This reply makes me happy in ways you wouldn't believe, and I really hope you'll be able to keep on keeping on. :)
I feel you, asking for help is really difficult. I've been terrible with that in the past, and still am now, so I completely understand your position. But the fact that you were willing to open up about your project on lumiradio already shows how motivated you are. I feel like identifying and working around your shortcomings is a good compromise -- you can work on your project, feel like you're making progress on a regular basis, all the while getting a clearer picture of what additional skills you'd need so that it's easier for you and other parties if/when you need outside help. And again, I'm not qualified, but the steps you've listed seem to make perfect sense to me (I've done roughly the same to select the narrative game development software I felt the more comfortable working in at present). What the engine allows you would be even more of a determining factor in your case, I presume, so that's really important.
Yay for Picrew! I'm a staunch believer in playing around with your characters in order to get a firmer grasp on them and remain interested in their stories -- but the type of games I'm trying to make might also skew my perspective. There's also a danger in thinking up a thousand what ifs and neglecting the setting you're supposed to be working on, but used as you said (as a visual aid) it is definitely serviceable.
(AZERTY keyboards are used in certain European countries :) It's normal for games to be developed with QWERTY layouts in mind, in any case. Duly noted re: difficulty, I'll remember to take deep breaths and calming walks :D)
May I follow you on here? There are times where I'm not often online for months on end, so it might not be timely, but I'd be happy to get notified about your future games (even if they're not THE project)! As for THE project: fight on!
