This game is a little hard to rate. There's clearly a lot of system work here to make it function in the background, but not all of that translated into a fun game.
A tutorial, or a text hint on how to use the power plug would have gone a long way to letting people explore the rest of the level you created. As designers, your game should be able to communicate its intent to players. I don't think swapping robots or lasso-ing with the power plug are bad ideas, just that without any way to get that across, people will leave confused, instead of happy and inspired.
As it is, however, i did get far enough in your game to escape to the title screen! It's cryptic and difficult to control, but this game is more finished than most! For that, be proud...but also mindful of the lessons learned.
