Hi Maverih21, thanks for taking the time to comment!
As for your questions—yes, the plan is to have multiple endings, although I hadn’t thought of them quite the way you described XD. They’re really interesting ideas though, and I’ll definitely keep them in mind.
Regarding the sprites: you have a good eye! I actually bought those assets from Angeler1234. Since there are so many frames, animating every single clothing change is a nightmare right now—that’s why the change isn’t visible on the 2D sprite when you put clothes back on. I might switch to something more RPG Maker-style in the future, or maybe not, I don't know yet.
I usually leave those big design decisions up to my Patreon supporters, but I really appreciate your feedback and you pointing it out. Thanks for playing!
