Highly Recommended!

There's a check-in event, plenty of hidden quests, so I highly recommend it. There used to be a time quest, but it's gone for me. If you're doing the time quest, definitely check it out. Even if you don't have the time quest, there are tons of hidden quests, so give it a try. The puzzles are moderately easy too. There's a hidden quest that requires watching ads, so you do have to watch them... Highly recommended!
