It's a pokemon go clone. But Nomura hates walking so he made it so you don't have to go for walks to make progress in the game. So the core genre is mechanically irrelevant.
It's also in development hell for no known reason. There was a closed beta 6 months ago, and a 2024 release date, and radio silence since then. The closed beta didn't seem to have any problems, so the game is either being completely reworked, or has been cancelled, or something else entirely.
