Very cool concept!
I couldn't make it very far though, I managed to get the robot from the first room into the second room but wasn't sure what to do from there. I also encountered an issue where if I used E to spawn a bulldozer while standing on the grey tile as the blue robot, the bulldozer would push me towards the camera and off of the line I was supposed to be on. So I then couldn't go back through to the first room. (Unless that's intentional)
You could definitely take this concept further though, with some more polish!
