There’s two ways to look at Kumobius’s “Duet”. You can take it at face value, as an arcade-style game where you maneuver two balls through a gauntlet of platforms. Kumobius also tells a story, however, through the chapter titles (named after the stages of grief), the text at the beginning of each level, and the gameplay itself.
Story aside, the game is simple. There’s a red ball and a blue ball that you can have travel a circular path. If you press the left side of the screen, they go counter-clockwise. Press the right side of the screen, they go clockwise. You have to maneuver around a series of platforms, and if you hit one, it’s back to the beginning of the level for you. It’s got a nice difficulty curve, with easy tutorial levels in the beginning and a decent challenge at the end. I’m not going to go into the story here, as I think it’s better experienced by yourself. You may find it inspiring or you may think it pretentious, but in a game like this, it’s best to form that opinion for yourself.
If you like the base game (free on Android, $0.99 on iOS), you can buy the premium version to get a level pack which expands upon the story, as well as two new challenges every day. On top of that, you can also spend another dollar to get the encore, a third level pack. If you liked the base game, I’d say you should go ahead and buy at least one of the expansions.
