Well, it's pretty safe to say this experiment did not turn out too well.
Our plan was pretty straightforward — its main point was not to compete with mods that "have a bit of everything". So instead ORGS Studio made a silly (and trashy at times) game that had LGBT pirates, forced transgender striptease and a Nobel laureate in literature as a game character in it. Reviews showed there's some people who would be into this kind of stuff, but the majority of players just weren't very impressed by this idea.
We think the game is pretty good, most players don't — there's no point in arguing, so we've decided to stop selling The Zombiest Adventures on Steam and return money to everybody who purchased it.
Perhaps the project will be repurposed as DLC in the future (with a lower price tag as well), but for the time being it's better to remove the game from digital shelves altogether.
