A Dance of Fire and Ice (2014)

Two orbiting planets turn corners into rhythm: each bend changes the spacing of your next presses. A single button keeps the physical vocabulary small, while the patterns ask you to hear how a phrase fits together. The built-in calibration matters because the timing is strict; this is a satisfying practice game rather than a forgiving background activity. On PC, the editor and custom levels give you more to explore after the official tracks.
