This game is practically worthless. I spent a few days playing but couldn't find any real logic to improving my abilities. It's mostly just button mashing to drill in a downwards direction as fast as you can while grabing some oxygen pills along the way. Each level i sconsecutively longer (not harder, just longer), and you get to unlock different characters along the way and use them to replay the same levels you've just completed. I only spent $10 on it from eBay and still sold it back as I was embarassed to even claim it as part of my collection.
