I'm really glad you're enjoying your time with the game!
-I do definitely want to add more sounds to her inflation, including having different sounds for when she's fatty or bloated! Like with a lot of other polish like that, I hadn't had the time just yet to get around to adding those, but I do very much hope to add them in due time ^^
-Due to the randomization of the shapes, fattening does end up chosing smaller values for the fatty features (especially the love-handles); I'm looking into correcting it so that it will give higher values more often or at least will have a minimum value
-Unfortunately upping the max sizes is completely untenable at this stage; it's already difficult to work with the mesh as it is, and adding the additional morph shapes required to get the clothes in particular to work with larger sizes will just make it near unusably difficult to do anything with >.<
-I will try to keep these in mind when improving the gameplay as I expand the game further! ^^
I very much appreciate the feedback, so thank you so much for taking the time to play the game and compile your thoughts about it! ^^
