Retro/Grade Released on Steam

Experience hours of mind-bending rhythm-based gameplay as you fight through space battles while time flows backwards
24 Caret Games has announced that its reverse-shooter Retro/Grade, previously released for PS3 via PlayStation Network, is available now on PC via Steam.
Time is reversed throughout the game, so you play through the game backwards. However, there is a power up that allows you to change the direction of the flow of time allowing you to undo your mistakes and repeat a section of the game that you just did. While using this power up, time moves forward at 2x, which acts like a rewind on a VCR. You do not have control of your ship, but you can rewind for as long or short as you'd like (provided you have enough fuel). For more information, read on for the detailed instructions on how to play the game.
