Current silence

cannot be judged

Our news coverage needs a fresh check; missing posts are not evidence that development has stopped. It is currently 30% below its usual price.

Last successful news check: Sep 27, 2026, 2:05 PM UTC. This is when we checked Steam, separate from when the developer last posted. A fresh check is needed before judging current activity.

We hold a thin slice of this game's announcement history, so its normal rhythm can't be established. That is a limit of our record, not evidence about the game.
