I'm actually feeling pretty optimistic about this.
Aquapolis turned out to be a lot of fun and I'm looking forward to more small group activities I can do with my FC friends.

The only thing I'm worried about is the low number of save files. It probably won't matter much for the first 50 floors since they've said you'll be able to get through them all in a couple of hours but it may be more of a concern once you aren't guaranteed to be able to finish at all if you have a lot of different people you want to run with.
