Quick infodump for anyone who wants to whow what to expect before they play the game
It's unfinished. There's about 3 hours of gameplay. And about 6 total instances of stuffed belly. Also, the largest anyone gets is about as big as a beach ball, in an optional event that cannot be repeated, but it's ok cause they prompt you to save right before it happens so you can reload over and over again
Since the game is unfinished, Archer's ass never gets fat as seen in the fanart. Do not expect her to gain much weight
While it is not the best Fetish game, it is still a great video game. The battles are easy, but you don't breeze through them. I have not died once, but I did regularly lose a lot of health.
Basically, try the game if you want to see Archer's origin story. It's really good at making you care about the characters.
