The original idea was to have the mc gradually drift from he to they to she through the journey, but people complained about they/them being in the game as being confusing, and so now it just jumps to she/her after the ritual.

Yeah it's honestly my preference tbh Sleeve Shock would've worked really well having an extended they/them phase, but unfortunately they/them isn't something super common and understood by people, for it not to be confusing in a narrative where you don't always get easy context to know who's being referred to. You'll notice I use the character's name a SHITLOAD for this exact reason.
