I can understand this, especially at launch when they want everyone to level through the new content. Heck I wouldn't be surprised if the new one is 60-70.
For Aquapolis I was pretty satisfied with how they implemented that and I hope they go completely crazy with it. My favorite moments with Aquapolis are the troll moments when you open a door. More things like that and bit more random things that can happen during a floor. Lol maybe also instead of the door failing to open the floor gets destroyed and you fall down to the floor below or... maybe en empty black void with just chests that are all empty.
