Latest update:
Talked with someone from MS (thanks again Jake), and the main problem was that I had a screen at the end that showed which Paths you had completed. Since I consider complete that you have done both the good and the bad end, the first time you play through it would be empty. I "thought" that if you had played VNs before this would be obvious (at least I've seen several games that did this), and since there was a big button on the side to start over, I figured even folks who hadn't played a VN would be able to figure out what to do. Turns out the tester saw a blank screen, assumed that meant it was broken, and so rather than drop me a note, just failed the app.
I have now replaced that with a full stop "You've finished this run, please start again" which I've been assured will meet at least that issue. I'm still not sold on the "Whack a mole" test model given that MS is paying these folks, but then no one is asking me.
I am also moving forward with a full RenPy version. First because I think this is a better version of the story and the game than the original "Senior Year", and because I can add a few scenes back in to a desktop version. It will still be All-Ages, but the current App is almost 41 megs, and for an RT user that is getting tight.
I am also pleased to say that since I now have at least one audition for each role, that I can announce that the desktop version will have all of the characters (except the player) voiced. That will likely push the final desktop version to around 100 megs. Still, I know a number of folks who wanted me to redo Senior Year just to get the voices again, and hopefully they will be satisfied with an improved version with voices. Of course having gone All-Ages made that easier too
Assuming I am done with Windows Store revisions, I should be able to get this out before the end of January. I would like it to be sooner, but I'd rather promise long and deliver short (I'm sure Jake and Papillon wish I had learned that lesson a little earlier, but oh well...)
Thanks again for your interest!
