Interesting concept, I like it. BUT, you shouldn't charge for it right now when it's this early in development, just do that "pay what you think is necessary" thing that Itch has. Maybe set up a patreon or something too but leave it at that for now until you get a couple more updates under the belt.
I'd also recommend making the Ai art more consistent so that there isn't a complete wardrobe change almost every level. Because going from that lab coat over a skinsuit to whatever the FMG 1 outfit is, is really jarring. As well as making it so that the MC's hair doesn't suddenly go from white to black sometimes or just completely change colors.
The BE route is a good example of what you should do. Her initial appearance to her level 1 is almost 100% perfect as it keeps her lab coat and makes her chest larger. The only problems is it changes her pants and turns it into a front flap dress of some sorts (no clue how to describe it) with thigh-highs. It looks good but it doesn't match her previous appearance. Then BE level 1 to BE level 2 doesn't work at all as she completely changes her appearance.
A work around would just be to mention that "the Bloom" can also alter clothing to some extent. BUT, you should keep it moderately consistent and slowly work towards whatever your ultimate goal would be. Having each level change her outfit slightly. Like maybe level 2 gets rid of the lab coat as it "can't close anymore" or something.
Another thing would be to maybe add actual text describing the growth the character goes through. The initial choice is the only one that gets this and it isn't that descriptive as it basically just says "your clothes get tighter." 2 to 4 sentences each scene wouldn't be a bad idea. Like what you did with the extra scenes for instance, the descriptions for those are pretty good.
Anyways, the whole AI game field is very difficult to get actual support for since they're usually considered "low effort" and the whole AI generated image thing has been the center of a decent chunk of drama on the internet ever since it took off around 2023. In order to get support for these games, you have to put more effort into it overall. Not to mention a lot of Ai games end up abandoned or are just incredibly low quality too. Taking the extra time to make the art consistent, write descriptions, and fleshing out the game's mechanics would increase the game's overall quality and thus get a donation or two as well as more support overall. There are some pretty good AI games on here that have decent followings you could take inspiration from too.
So yeah, that's what I'd recommend. And I do understand using AI art btw. I'm not an artist myself, and I definitely can't afford to commission someone to make art for an entire game either. So if I ever decided to make a game, I'd probably use the default assets you get from RPG Maker, Koikatsu, and Honey Select or just AI generate everything depending on what kind of game it is.
