    iO is a fun enough diversion to play in between games, but it’d be even better to play on a phone so you’ve got something to do while waiting for a lengthy load screen to complete or the next Overwatch match to begin. As such, the Vita version may be the better option of the two. It is fun but not particularly memorable, to be completely honest. As per usual for most mobile-to-console games of iO’s ilk, it is best enjoyed in short bursts or as a means to kill some time.

    Though far from revolutionary, iO is a simple, yet intuitive puzzler that is sure to dig its hooks into fans of the genre looking for a unique challenge.

    Overall then iO is a decent puzzle game offering loads of content, it’s also cross buy with the Vita which is nice. It suffers from some proper hard difficulty spikes and relies a bit too much on trial and error, but at the end of the day it plays a decent puzzle game.

    iO is a solid physics puzzler with simple controls, minimalistic visuals, and challenging gameplay that comes together as an overall decent experience. The tough difficulty spike and puzzles reliant on trial and error and good luck prevent this from being an excellent title, but if you are looking for a game to roll you over to the next big release then this is certainly worth a punt.

    iO is not a memorable game. The good news, I suppose, is that being thoroughly forgettable also means that it's not memorably bad, either, but if that's the game's major selling point, it should tell you how far away you should stay.
