Hide and Seek is currently limited to Level 20.
Because you can’t progress further from Level 20, new levels will help to increase players on it, especially as it currently peaks (on EU when I’m on), at around 500 players. Though this is quite good, adding more levels to progress will help to bring even more players to it.
-I’m not sure what cosmetics, etc, could be added, but please just vote on whether you think this is better and will improve, or not.
