Congratulations! 6th Anniversary (Late Celebration)

Proseka has finally reached its 6th anniversary!! Congratulations indeed!🎉 I invited my friends and got rewards, but there's one thing I want to say. I feel like the rewards are a bit lackluster, or something... I only really want the 500 crystals and my favorite character's pure crystal... I'll keep playing with the hope that they'll give us more crystals.
