thats not as hot... in my opinion.
I don't know it doesn't look like Noa's even paying much attention to this concept anyway. it has been almost a month and a half and still no reply from him... oh well the dude has a lot on his plate and we (me especially can't just expect him to add a new feature butt or otherwise. oh well maybe next update
He is paying attention but Cowtastic Cafe is a side project. Nearly 4 months ago he had replied saying other expansions are basically off the table. One suggestion was for multiple sets of breasts, but would take a ton of work. Another was for hip/thigh expansion but the barista does not have legs drawn and she's hidden behind the counter so it would be fruitless to add those features. Same could be said for belly, as he said pregnancy is not an option either.
