Don't think it has been abandoned, its put this on hiatus and working on a new VN called Lust. Last update the creator gave said they needed a break from this VN for now and is only working on Lust but will be back at some point.
Viewing post in Uncommon Breed (A Furry RPG / Dating sim) comments
Well, I respectfully doubt that. Lust seems to go into the same technological debts and difficulties like UB ended up in:
Extremely shoddy coding, full of bugs, one fix per month if any, minimal communication, hides behind Patreon/private discord for payers, disables comments
And for Lust specifically:
no polish in any way since first build (GUI, visuals, glitches, dungeons), only one new character per month (probalby commissioned with Patreon money to keep the train going)
I encourage everyone to stay clears as long as the creator does nothing to communicate and better the situation of his projects.
