Lost a lot of time thanks to the surgery, but you'll be happy to know I still managed to get a little bit of planning at least when I could not actually write anything. Even next year's CYOA Snow In Summer has some rough plans! I made myself a rough floorplan for Gungjeon Mansion where the story will take place! The skills you can learn to prepare for the heist are going to be; Magic(TF), Lockpick, Medical, and Deception. Your skill remains a static value to try and match the difficulty of the action you are attempting BUT, there is also a Luck stat. Luck will be a random roll between -1 and 1. So if you have a Lockpick skill of 3, the lock is a difficulty of 3 and you have bad luck, you'll fail to open it, because your skill thanks to bad luck is effectively 2 for that particular instance. I made it so that luck mixes things up but cannot put too much weight on RNG- if you are a savant at Lockpicking then all the bad luck in the world still won't make you fail. I also will not say with a number exactly how difficult the skillchecks are, so there is a sense of tension and forces you to be smarter about how you go about it. Y'know, like an actual heist.

As for endings- much fewer than the first CYOA that is for sure, haha. This is a set path- a story to follow where the first CYOA was more of an open experience where you could kinda just wander off and do whatever you want within a time limit. The endings for Snow In Summer will be;
Failure Ending : multiple versions of this but basically the same thing- you fucked up
Bittersweet Ending : you get caught, but still remove the gem from the owner so you... half-win
Normal Ending : you gone done it.
Perfect Ending : holy shit you beat it so hard you uncovered a second plotline
Absolution Ending : ?!?!?!?!

As for the upcoming Year's End Finale (which I now realized I have roughly 10 days to finish, oh crap), it will have 6 chapters;
ch1 Like Riding a Horse (horse/wolf hybrid)
ch2 Holy Cow (cow)
ch3 Street Rat's Revenge (rat/snake hybrid)
ch4 Doom Song (crane-like bird)
ch5 Stone Cold (gorgon)
ch6 Operetta In E Flat (final battle for humanity)
The entire world is being transformed so there will be a bunch of background transformations all over the place too, but these are the main ones.

And the chapters in The Shape Of You are also planned out- there will be 7 but since I don't start working on it till next year; the chapters are not named yet. BUT, it will work something like this;
ch1 Intro, the characters, their home town, their families- they set out at the END of this chapter.
ch2 this chapter showcases the many problems they have with their current forms, both with recounting old events and encountering new ones on the road
ch3 Quinn's dedicated chapter, and a look at his alternate form
ch4 Avalyn's dedicated chapter, and a look at her alternate form
ch5 Nelly's dedicated chapter
ch6 Revelations
ch7 Arrive at the city to make their wish to Astrelle

Don't worry, it isn't all story! In addition to them all having an alternate form (or many in Nelly's case), there will be a sex scene for Nelly x Quinn, Quinn x Avalyn, Avalyn x Nelly, and all three together.
So yea. A bit of a preview of things to come.
