Puzzle games are a difficult genre. Because of the relative simplicity of devising them, there’s a lot out there. iO is a pretty simple game at the root, as well, but there’s some great complexity lurking underneath. Playing iO consists of one simple goal: roll a ball to the portal to complete the level. The ball has two control mechanisms: left-right movement, and size adjustment. Combining these two relatively simple controls during play is tricky, and you’ll have to learn to make changes on the fly if you hope to succeed.

XBA says: Momentum, size, and speed is what matters in iO, a game that you shouldn't judge by its visuals.
