I loved it. I think it is a great progression from the battle passes which personally felt far more grindy and exploitative.
I really like the detail the put in to all of the little art works and sprites, and the minigames. You can tell it has taken more time with likely less profit than the battle pass system.
My only qualm is that because I wanted to follow the story, I wanted to complete an act in one go cos otherwise I will just forget. That meant I was just hording tokens for ages and not really participated until the last week.
