Gorogoa (2017)

Sliding illustrated panels together can make a picture become a doorway into another scene. That physical arrangement feels particularly at home on a touchscreen. The paid iOS and Android editions provide a short, complete puzzle story; the iOS minimum is 9. It is worth choosing for the quality of those discoveries rather than a huge hour count. A tablet gives the intricate pictures more room, but the interactions do not require rapid virtual-button presses.
