Good to hear you liked the game! ^_^
A remake seems unlikely (it's the kind of stuff that would take me years, most likely). I am generally more interested in making new stuff. I guess never say never, but I wouldn't count on it.
I generally do listen to public suggestions, although at this stage it's less likely I can take the time to do so. If you are talking about the milking machine, it's been part of the Zanti path itself for a while now (although it wasn't there originally). Maybe if your original save file is a bit old, you didn't get the chance to receive the milking machine.
As for special uses, I'll consider it. As I said, it's a bit late, especially when it comes to introducing big changes. The game might get a 1.1 patch a few years down the line (if there is interest for it) so maybe I'll add a note about your suggestions and consider them for that eventuality, instead.
