A very interesting point you brought up, Tlaero. I love your focus on the narrative and it doesn't bother me that it's 'too linear'. First of all, you never said that these games in Elsa-verse were about decision-making and consequences. Basically they are dating sims but with a great overarching story (and amazing art thanks to Mortze). Most dating sims are fairly linear where there is only one correct path (with a few 'adventures' to choose from) with several checks for amount of points.
With many games that I played (not just erotic ones), I would say that the games with different paths work best as stand-alone projects and won't work as a connected series. They tend to either make decisions very small so the changes are purely cosmetic or they would ignore/retcon some of the decisions away with some bs explanations so they could railroad the player into the story they wanted to tell. And it sucks even more if the story ends up being lackluster (the notorious Mass Effect 3/Andromeda disaster). I wouldn't call that player agency either because in the end player decisions don't have any impact on the story. Not to mention it takes so much time/effort to write all the different paths.
If you plan on making a single self-contained story without sequels and such then you can really have fun with all the different paths and endings and the beauty of it is that you don't have to 'canonize' a certain path and the players would be happy that it was 'their' unique experience. Otherwise, better to opt-out. As for Saving Chloe structure, it looks interesting and I know I would have fun figuring out different scenarios and trying to guess which one is canon.
Off-topic: is there any chance to see you return to your old projects and, say, do something more with Christine? Unlike Keeley, she was only in one game (as a main character) but she will always be in my heart. I don't even know if you're allowed to since you don't work with Phreaky anymore. I guess I'm kind of curious what the game with her would look like now that you're much more experienced and paired up with Mortze.
Thank you.
