I have to admit, I underestimated this game. I thought it was just another lazy game with AI muscle girls (which is not bad in itself depending on what you're looking for), but a few hours into the game I was having so much fun with Gina and her friends. This game reminded me of the Persona games in the best way, where you have an interesting story while also having fun characters that you want to spend time with. So much so that I got genuinely upset at Jade's storyline where all I wanted was to protect that precious redhead. And Gina might be the best protagonist of this type of game, partially because she is hilarious, but also because we have a proper hand in shaping her personality, which so many "proper" rpgs forget about.
If I have to criticize something would be the combat system. It is well built (especially in a engine that is not famous for its combat), but as some people pointed out in the comments, I feel like all we're missing is some tools to give some depth to it. The enemy positioning system is a good example of a tool that this game does use it well. In that sense, the Persona games (especially the older ones) are a good inspiration, since they can be really difficult, but become easier when you take advantage of what the games gives to you. I'm don't really enjoy "AI art" a whole lot, but clearly a lot of effort was put into giving the images more personality than Ai tends to have.
Also, the game clearly improves in every sense as it goes along (as it tends to with independent games), Game mechanics, story and sprites/animation, so even if the beginning starts slowly it quickly picks up the pace, but it does require more patience than the average ren'py game. So if you just want to see girls growing it might not be the best first option for you, but give it a try if you want a cool game that happens to revolve around muscle girls growing stronger. On a side note, I do worry about the size of the sprites in game, because the girls are already starting to occupy a good chunk of the screen and I don't think like we're halfway their growth.
Overall, It was really fun and a bit stressing (the good kind) during act 2 and I really hope it gets completed. Now if you excuse me, I'm going to arrange the wedding between Gina and Jade that is definitelly happening in one of the endings (fingers crossed).
