1UP gave 5/10 to the PC version while giving 5.5/10 to the X360 version:
"You may -- or may not -- notice that the console version of TimeShift is '0.5' better than the PC version. Why is that? The controls. The manual override for your time powers makes enough sense on a gamepad. Hold down the left bumper button and punch one of the face buttons. Bam! You're in rewind -- or whatever. But the developers shoehorned that same button combo onto a keyboard and mouse.
That's right -- it's a first-person shooter that's better without a keyboard and mouse. Try using the time control mechanic on a PC and muscles you didn't even know you had start throbbing. While you're reading this, try using your left hand to hit the "F" key while holding down Shift. Now imagine attempting that while running around during a firefight. May I direct your attention to Crysis for a sec? Forget all the frosty graphics -- just take a look at that game's supersuit interface. A radial wheel menu opens with a press of the middle mouse button. Score one for intelligent game design! Seriously, guys -- considering how long it's taken to finish TimeShift, I'd expect flawless controls."
