This is an interesting take on the theme, as well as the build style game. I enjoyed building, though I wish that when I switched between play and build it reset my build so I could continue working on it. The reset button resetting the whole thing was a bummer. I couldn't figure out the rotation buttons either, they didn't appear to do anything for me.
I agree with what others have said though, connecting things is intuitive and rather easy. Well done overall!
