According to one of the reddit posts, the devs said they're still working on the game, so that's good news. My guess is GameTrust is dead and they've "cancelled" their release of the game, so it'll either be self-published or get picked up by another publisher.Looks like the PSVR Exclusive "Star Child" has been cancelled for some unknown reason, and pulled from the store. Their Twitter account has yet to acknowledge any cancellation.
Just a bit of a downer for what has been a great year for PSVR.
