I love the new stage. A giant cruise ship with a bunch of areas connected in multiple ways. It's perfect for exploration. But that's basically ALL it's for, since all 3 of the new missions are basically variants of the same formula. First it's just a regular scavenger hunt, then it's a timed delivery mission, and then another scavenger hunt, but now the boat is capsized (which tbh is a REALLY cool idea, albeit one that comes with some camera problems). There isn't even any new bosses, or hats, y'know the thing the game is named after, to play with. The time rifts are decent challenges.

So the new stage is fun and has as much charm as any other world (I love the seals), it's just kinda short and lacks diversity in the missions.

As for the "deal" part of this, it's perfect for people craving a true challenge and completionists. For me it was something that I knew I wasn't gonna 100%, so I didn't feel like there was any benefit in doing many at all, y'know? I like the idea, and admittedly I had some fun with the few I tried, just not for me.
