Thanks! It's coming along, I'm hoping to finish up a visual novel release soon.
I agree art would be kickass, but sadly costs money. The twine game will never have art, that's just an aesthetic choice. But I'm hoping to start adding art to the visual novel. I've just never done it before and it's a big expensive undertaking.
Edit: I did actually get transformation art! https://twitter.com/inkyfluffsdraws/status/1266150774888976385?cxt=HHwWgsC-lfzao...
There's also the fan art I commissioned on the first page of the twine game.
