Wanted to get this small achievement before Ririka (and eventually Hajime/Raden swimsuits) come out, since the leaderboards will be way more difficult. Happy I managed to achieve this for at least one week!
People are still figuring out the general strategies and how to play the game. once people have had time to figure things out and the game is in a stable state, the balance issues of the game will be more apparent.
Also I'm sure the development team is collecting data on the game (win rate of each side over time, how many points people are getting on each side). It seems like they are pretty receptive to feedback and incrementally balancing the game.
Any complaints about the fairness/balancing of the game are just completely premature and jumping the gun right now.
