Played v02 and I love this! Love the growth (curvier, muscle, height, cock/ball size, all of it) - wasn't expecting her to get taller but I'm super on board lol. Super into BE/futa so this is totally my thing. Also no issue with the other girl becoming a futa - interested to see where this goes. They each get bigger? Different growths (different proportions grow)? Competition for growth? The new girl stays the same size and gets humiliated? One's flawed and she gets curvier but shorter? The non-futa girls start to change? However it goes, will keep watching this.
Also - sorry to the guy above me but I'm going to disagree, I love them growing to ridiculous proportions and would encourage things getting absurd. I feel like the continual growth is a good incentive to keep playing, I guess? Plus now that there are other futa there's an aspect of comparison (so now if her cock gets bigger, it will additionally be getting bigger relative to the other girls too). Looove it!
Anyway - just want to say that you don't need to take any of this to heart OP! Keep making what you want to make
My only suggestion is to avoid all the girls turning into the same body type, as whenever that happens it kind of takes away some of the impact that their body type has (e.g. when all the girls end up having extremely similar bodies but different heads). This might not be as relevant for a game with transformation though, especially considering that even if they end up the same, the growth adds something new. Variety is great!
