There’s a feeling that’s difficult to shake when playing Paradox Shift. It’s that sense that you can’t wait to see how it will be implemented in Portal 3. Time travel surely comes next, right? The student indie project from the University of Southern California and the Laguna College of Art & Design has been mentioned in the same breath as Narbacular Drop and Tag: The Power of Paint elsewhere, and it’s tempting to agree. So I’ve had a play of a bit of it. And while it doesn’t have a feature quite so novel as portals, it’s certainly a far more engaging implementation of first-person time manipulation than previous attempts from mainstream gaming. The concept – moving between two time zones, tagging objects and transferring them between the two, in order to solve puzzles – is very intriguing. The delivery is already looking impressive. There’s some thoughts below.
