Really enjoy the game - love how much detail is in it. Only issue is that locking lots of the transformations behind classes is weird since they all are at the same level 1/2/3 so it's immersion breaking to just unlock classes for the sake of transformations. I think the best transformations implemented currently are the ones related to in story choices/character side quests. I think you could keep 1 change per rank of unlock (1st after the generalist one), 2 and 3. And link those other changes to in Act events or story moments. Would still keep the option to opt out (like the squeeze through one/look at clothing one) - but feels so much more organic if the transformations were consequences of choices in the story rather than most being just unlock the 12 classes.
Would also love if there were more references to the MC changed appearance, some more romance stuff or if the image of your clothing updated as your body does.
