How's this game an "idle"?
That's just the closest tag you can pick for this type of games, it's not idle, but it requires minimal effort to play it. And since I'm getting a lot of traffic from it and none complied since then, I guess this is in a way what players on #idle are looking for too. I get that not everyone will be happy with it, so sorry for that.
I also see every active incremental game uses this tag, so I went this way too.
