We started Chapter 5 of Mice & Mystics late on Sunday afternoon, but only got through the first room before we had to stop for the evening. It is still sitting out, waiting for us to finish it.
As with any game, there are good things and bad things. I like the game quite a bit, but my biggest complaint is that, at least while playing with kids, getting through a chapter can be a bit time consuming. This one is seven rooms long (I think).
Fortunately for me, my oldest daughter is eager to keep playing.
