OIO is a 2.5D platformer with a pretty fresh plant growing mechanic. So basically you wander through well designed fantasy levels, collect orbs and scrolls, and throw seeds at green plants to make them sprout beams. Jump on these beams to reach higher grounds or use them to solve puzzles in the later levels…
An overall really enjoyable platforming experience.
In total the game offers 12 levels and I think that it takes around 2-3 hours to finish it. Consider to check it out by yourself or watch a playthrough of OIO on YouTube.
