Assembly should be much easier and clearly marked. A 5-6 year old needs an adult to do most if not all of the work. The thin plastic rods have to go into a very specific and poorly marked hole on the ball joints. You can only build a few small forts with 1 kit, and to build bigger forts you need at least 2. We almost never use it because it's not easy to build and the time it takes playing an hour, is not worth.
