While I don't see this event ending up being worthwhile (they're nibbling around the edges rather than making any significant change), I DO very much enjoy the mini-game. I know a lot of folks are unhappy with the time required, but the same could be said for things like Daily Challenges. I actually wish I could play the mini-game more; I can't because of the damn PoG limitation. I would LOVE to see the mini-game put into the "main" game in a repeatable mode, possibly using FPs in place of PoG and with prizes similar to Daily Challenge chests when you complete a game round, similar to CS.
Anyway, sincerely hoping Inno does keep the idle game in a repeatable feature outside of the Event. The idle game itself is a lot of fun IMO, I just wish the event was better balanced, the chests carried over, and the fillers weren't doubled.
