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.
If you're craving a decent platformer then this might be a good option, but there's plenty of similar games that offer more.
All in all, iO puts together a simple but effective package that presents a wide skill range of available puzzles. With plenty of variety to the obstacles you'll face, there's lots to do no matter which type of puzzle you're best at.
A straightforward puzzler that borders on the fiendish as you progress. If that's your thing then iO will definitely be in your wheelhouse.
A simple-on-the-surface, yet tough to master puzzle platformer that will keep you coming back time and time again to obtain the best medals that you can.
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.
We both had a lot of fun with iO. We're big fans of puzzle/platformers (and platformers/puzzlers) and this release on PS4 and Vita does the genre justice. There's plenty of content to play, not to mention a ton of hard levels that will leave you scratching your head for a bit as they almost demand perfection from you. We highly recommend that you give this one a go either on PS4 and Vita since we're sure you're going to love it.
iO is a simple arcade game that requires us to transfer a ball from the start to finish. It can go faster, go slower, grow and shrink. We can play on enormous number of levels varying in difficulty and complexity. The only downside for Xbox Players is that game has broken achievements that can't be fixed with an update. Shame.

iO is not a complicated game. If anything, you (as the player) are the most complicated element in the equation as the protagonist, a wheel left to the merciless truth of physics, gravity, and momentum.
