As for the second puzzle room...well, it's mainly an issue of aesthetics I suppose. It just appears kind of silly to have all of these towers and stairs inside the building. It would make more sense if they were outside. It doesn't look like anyone is trying to make it hard for them to get out of the tower anymore, and instead it looks like a giant children's playhouse. All that's missing is the ball pool. Again, maybe this is just me being a stick-in-the-mud having gotten used to the previous versions, but it doesn't seem like the puzzles are trying to be as challenging anymore. Still, it's your game and you can make it however you want. I don't have a problem with that and this is only my opinion.
