Stop the plans of ...? Something missing there? :P I do appreciate the dual controls, guess I'm somewhat ambidextrous there since I wasn't sure which one I would want to use... but the arrow key setup worked great. WASD worked great too. Those two variations seem to be the two most common key combinations in games, and most use just one of the two so being able to freely toggle between the two is a great advantage over other games!
As for the game: love that 'Drill with it' slogan. XD The captain obvious signs too, the think-of-the-children drilling, appreciate all fun wordplay and detail. Controls are slick, and running around drilling's all good fun, even if I was expecting more of a Motherload type drilling game. You know, mine resources, go downwards... graphics are nice and pixely, there's a little story mixed with the gameplay... there's a catchy chiptune. Apart from the overly elaborate title (doesn't seem to fit the simple theme/graphical style... I guess) I find no flaws. Nice work!
