This is a very interesting gameplay loop, a sim with a robot that wants to mess you up.
I did have quite a few problems with assembling, and there were times when I couldn't pick up stuff I needed. However, I think this is a difficult design to implement, and it's amazing that you were able to do this.
Another problem is that when spam clicking objects or the robot puts stuff somewhere, the parts can be difficult to see and grab. Adding a limit to where parts can or cannot go can be useful.
Great job, this game was fun and unique!
