I know it's just a game, but still... The MC wakes up one morning with bonet D breasts and a porn star ass. The game is not about miracle pills or magic, but about a simple standard hormone therapy treatment. It normally takes months to get an A bonet and the MC only realizes now that he has the body of a well-developed woman?
If the author wants to stick with the overnight transformation, I'd recommend finding a more science-fictional reason.
For example:
Spell. Or miracle pill taken inadvertently. Or technological/extraterrestrial implant installed without the MC's knowledge. Or when it exploded, a university professor's failed invention projected a feminizing ray onto the MC, but the effects didn't appear until the following day. Etc... There are many serious or zany reasons that would work. The MC would therefore arrive in prison with a woman's body and already pronounced curves. No need to redesign his figure.
Otherwise, I'd recommend a gradual transformation with a more credible excuse than "I took my mother's medication for 3 years without either of us noticing".
For example:
Noticing that his body is starting to change (sensitive breasts beginning to enlarge, A bonet and not D, finer facial features, etc.), the MC becomes concerned and tells his doctor. After various medical examinations, the MC discovered that a new molecule, used in the manufacture of his treatment, had triggered intensive estrogen production in his body. From there, we pick up the thread of the original story (despite treatment discontinuation or change, feminization intensifies, treatment to halt the process is too expensive, etc.). The MC would therefore arrive in prison in the early stages of feminization, rather than with an already curvaceous female body. But this means redesigning his current appearance.
In any case, the beginning needs to be rewritten to give the game a minimum of credibility and appeal. I'm waiting to see the next updates and will adjust my rating accordingly.
