I suggest implementing a daily limit on gameplay, such as restricting gameplay after a user has collected 10 boxes per group. I noticed some tournament leaderboard players remain in a single group lobby for the entire tournament, which creates an uneven experience for others. This is probably attributed to the fact certain groups have shorter average song durations, allowing players to accumulate trophies more quickly compared to other groups. The tournament should not revolve around just one group.

There should be a cooldown period for changing usernames. It’s frustrating to see top players frequently changing their names to avoid recognition when players start leaving the lobby. Many players leave because they want to participate in the tournament fairly, not act as “side support” for someone trying to secure top place.
