Fun game, but if you aren't creative or good at building stuff with minimal guidance it can be on the difficult side. The little test robots can be kind of stupid so something you think should work just won't sometimes, which was kind of frustrating. I liked how they made a story out of generic Lego building that wasn't for a licensed franchise and you have actually quite a bit of freedom to build stuff as long as it fit the criteria and didn't topple over in the test sequences.
