I'm really glad that you stuck to one mechanic, and did a lot of different things with it! That's rare for a ludum dare game. You could probably deepen out this mechanic even further by allowing you to smash through things with the plug, use it as a sort of lasso to drag items, and so forth. A really nice base for a game that could turn out very solid.

Damn it was good. it was so good. Dudes, don't let your game stay in unrated games! Play other games and rate them, so the LD site will show your game to others.
It was the coolest games I've ever played in LD. I wanted more levels as I saw the "Thanks for playing" screen. This game is worthy of every award. keep working on it.

And also, Add some screenshots to your game page. It's very effective.
