Our little one loves fortresses and just pretends to do different things so this concept was really cool. I wish it had more assembly instructions but again, just use your imagination and think ahead to make sure you have enough pieces, we're thinking of getting another set to make constructions of different heights to make and erect walls. like a theatre. We have already built fortresses and a rocket ship for them. Just a reminder to watch where you insert the rods into the ball as the ball has two directions with the same hole pattern which is my mistake in the first fort.
