Just to add a bit more clarity on what's goin on. The developer is working daily on the game's development, despite some exhaustion slowing progress. They've realized the game had become overcomplicated with too many past event references and decided to simplify future plans by cutting unnecessary group sequences and focusing on one-on-one experiences. They've moved and removed some planned content to streamline the current build and reduce the workload.
In reference to side content, they have been holding off on the monthly gallery to focus on the next build. And while voting is currently going on for the Grind'm update, the Dev build is their current focus.
