I love the worldbuilding and overall story of the game so far. Each route makes your body tingle, you know?  The growth scenes are a 10/10 and would love to see more. I want to see how much Jessica and the others change in the next update.  It is not only their bodies but you can also see how their personalities change with each dose of the serum. There's not a single grammar or spelling mistake I've seen so far. Yet, in some areas, I think there are some places in the game where it could be improved. Particularly, not that i wish to burden the game dev with more work, but I wish sometimes that there were images appropriate for some of the actions. The way the growth is described in the text could also be improved, but I think the growth scenes more than makeup for the flaw. Despite all that, this is the best fmg visual novel yet! I really hope the game dev doesn't abandon the game like most game devs do with their projects in this kind of games. I would really like to see the game fully to its end. Lastly, not completely necessary, but i suggest you do some kind of progression updates in discord or deviantart as to not keep people guessing. Me in particular is always afraid that the game will be abandoned at some point due to the gaps between updates afterall. I don't care too much whether the updates take too long, but i hope there's some kind of reassurance that the game is still being worked on.
