This game is already excellent for an alpha! I appreciate that it doesn't go into hardcore stuff and still (kinda) respects its characters.
I have a few questions/suggestions... Is it planned to have more than three playable characters, or maybe other outfits ? A secret condition or NG+ where you get to add Livia to your party?
Additionnally, why not have some new designs a bit more covered by clothes (full torso or just the breasts, Ran seems to be a step in that direction), so that when their bodies swell, you can feel the fabric being stretched (with maybe the biggest variations making the buttons completely surrender)?
About the dialogues, adding some additional ones based on the state of their body (like feeling heavy, massive, aroused, kicked, etc) would be great!
There, these are just ideas that came to me, I understand if it feels unreasonable to you. Anyway, I'm eager to see what will come in the following updates.
