I'm very happy to hear you're interested in Mable's story! If/when I get back into this game, I'd like to make that happen.
The game asking your body type is more just to set something up quickly in case you don't want to go through all the options. It's not difficult to set up or anything.
Less adjustable kinks mostly has to do with me understanding better now what I'm capable of making, and what's viable to allow the player to turn off (since having to account for disabled kinks can mean a lot of extra work for me.)
Will neither confirm nor deny your head canon XD
