Very polished and enjoyable game! My biggest complain is also the tedious element when it comes to watching the robot move or drawing out the path. The puzzles that are in the game do have a nice progression, so there were no frustrating levels to be stuck on for me.
The concept is very interesting and fitting the theme well. It could be extended massively through interactive elements like doors, switches, jump pads, the mind goes wild with that. :)
