2D sidescrollers are awesome, and there have been some pretty good ones making a debut recently. Soon to be added to the list is Rochard, in which a space miner kills space pirates in space. New screenshots are out, and posted for your viewing pleasure.
This game looks cool, and I love sidescrollers. And physics puzzles. I love those too. Rochard is scheduled to hit the PSN later this summer and will be $9.99. Buy it. Solve puzzles in space.
