If you are not into games that feature endless tutorials, but are more inclined to go for the ones that are minimalist, yet challenging, you should definitely take a look at the newly released Duet Game.
It doesn’t take long to get familiar with the game. Two colored dots – a red one and a blue one – revolve around a central point. Your job is to overcome obstacles, which is fairly easy in the beginning, but later on becomes increasingly challenging. The game, which features an impressive soundtrack, requires complete focus, if you want to successfully master all 9 levels.
