I think I understand where you were going with this, too bad the robot parts weren't working, though. I feel the first couple things were just tutorial levels, and none of us could play the non-tutorial levels.

I understand the idea, and it's a good take on the theme. It's a bit too simple to attached the parts to each others i think, maybe you could add a welding system to fix parts at the exact place the player placed them, and the score could be determined by how far the toys are from the specification. Also, the tutorial is well handled. Nice job !

I liked the in-game tutorial. At first I tried assembling carefully but when the parts where scrambled I jammed them all on the workbench and picked up the head and sweeped over the workbench. Parts attached magically at the right joints and I was able to get a score of 50 there.

I wasn't able to build the fat toy, the parts wouldn't move to the bench.

Good job, appreciate the fat mama joke too!
