RELATED: Help, I've Fallen In A Hello Kitty Gacha Hole And I Can't Get Up! Underdeveloped areas in the game, a Tokyo city quest which was announced but never actually delivered, and underwhelming physical release sales all led to a dwindling player base and set the stage for the game's disappointingly premature poof out of existence.
Sadly, these efforts didn't amount to enough. Reports suggest that Sanrio Digital became increasingly less attentive towards their game, which started frustrating players. Many began quitting it, for good. Out of the ones who stuck around, some tried to encourage new players to join, while others tried to contact the developers and get them to step up to the table.
