Most people don’t appreciate unfulfilled promises, and the developer wasn’t obligated to make any in the first place. From the summer until now, we received two explicit confirmations about an upcoming update. Naturally, players expected it to arrive, because they were given a clear indication that it was on the way ... so their frustration is entirely understandable.
After that, however, communication shifted to a few brief appearances with some screenshots, without a release date, timeline, or any concrete information. From my perspective, the situation has become somewhat ironic, almost comical in a way but I’ll refrain from commenting further.
