ok but i mostly ask if there is a possibility for the mc to remain a dickgirl or even become more dominant and get bigger dick, height, boobs etc
The MC's dick shrinks almost immediately and at the end of current version that's where they're either stuck: feminized, with budding breasts and a micro-dick, or they've leant all the way into transforming into a woman.
The dialogue is very clear that halting the transformation pauses it
as it is with no way currently of going back. It sets the MC up as a femboy with potential for humiliation scenarios and the like, but absolutely not as someone capable of any sort of sexual dominance. (Of course the plot may develop from there later on.)
There are some choices in the game, but it is unclear (without looking at the script) how much they actually affect for now. The MC can say that they're not into a guy at all, and the narration will still go on from there about how they're constantly thinking about him.
