The start of the game is dense as I want to make sure the trajectory of each route is firmly established with the first week of showing what Zach's day-to-day life with a female body (and hiding it) looks like with classes, romance/sex life, extracurricular activities, and social life so that readers can fill in the gaps made by timeskips of a few days or even a few weeks. All routes will anchor loosely around holidays and school breaks, most notably Halloween, Thanksgiving break, Zach's 21st birthday (December 7th; the game starts on October 7th), Christmas, winter break, New Year's Eve and Day, Valentine's Day, and spring break. While not getting into spoilers, each route will have additional focal points (e.g., Britney with the theater club and visiting her family for Thanksgiving break, Keisuke with the swim team), but the game will have an epilogue starting from when the re:Dreamer season ends at close to the end of Zach's freshman year to a few weeks after he graduates so the story ends with a clear idea of what's next in his life. The game can't realistically end with Zach changing his body back due to Zach using his wish for something else he sees as being worth more, but just because this character keeps a female body won't necessarily mean that he will be a woman even though that's probably what most readers are going to get because of the story choices they made.
Once again thanks for answer, that satisfied my curiosity and even provided more than I was expecting. Wish you all the best on your project. Really exited for what waiting for Zach/Zoey in the future.
Also worth mentioning that I found its interesting on having to hear different perspectives on the same event (I'm taking about MC mom escaping to meet up with MC dad). In my opinion that is something that I would call surprising but not unexpected when you think about it
