    The gameplay of Io is characterized by its unique mechanic of resizing the wheel, which influences speed and momentum, providing a fresh take on puzzle platforming. While the controls are generally intuitive and the level design is engaging, some players noted inconsistencies in the mechanics and a desire for more variety in gameplay elements. Overall, the game offers a solid experience with a good balance of challenge and creativity across its 225 levels.

    • “Even with the simple mechanics, there are a lot of tricks available to take advantage of and beat the level.”
    • “The gameplay is intuitive to learn, and most of the mechanics are very intuitive, though some will require some practice to get used to. You will also spend time trying to beat puzzles through trial and error.”
    • “The game's unique mechanic is the ability to change the size of your wheel, which affects speed, size, and weight.”
    • “However, I can't help but feel that even though the game is aiming for a more minimalist approach in graphics and gameplay, it just never felt like enough.”
    • “Sometimes the mechanics didn't seem to work, like you are supposed to grow when going down and shrink when going up, but shrinking actually slowed me down sometimes and growing slowed me down sometimes, so more consistency could have been nice.”
    • “Core gameplay is a bit lacking.”
  • graphics
    21 mentions Positive Neutral Negative

    The graphics of the game are characterized by a clean, minimalist aesthetic that many players find beautiful and relaxing, enhancing the overall experience.

    • “I like the game, but I got a new computer with an NVIDIA GTX 1070, and for some reason, it ran better on integrated graphics. Any suggestions?”
    • “With the pretty simplistic game graphics and mechanics, a level editor will be a really nice addition to the game at a later stage, allowing the community to go nuts, but for now, I think trying to ace the 150 levels is more than enough.”
