Took a few tries and kept losing items that clipped outside of the play area. I think it took 2 full rounds to realize that the arm attachments were tools as they didn't match what the picture showed for the tool. Once I figured that out I was able to successfully build a vacuum cleaner. Having to use two hands was annoying, but if you intention was making a game like Plate Up I can see having the second arm be another player. The randomness on which bench needed to be used was kind of annoying, but I understand to make it more replayable.
