har•mo•ny is a puzzle game that merges color and music in perfect harmony. The objective is to rearrange blocks according to a palette of colors that blend together in harmony. The game is designed to be simple yet deceivingly complex, with blocks moving only horizontally or vertically, and each block must use up all its moves. With sophisticated color palettes ranging from simple boards with 3 colors up to incredibly challenging 10-color boards, the latter levels are insanely hard.

The game is accompanied by elegant background music and harmonized sound effects, making it a truly immersive experience. The game features over 1000 beautiful levels, each with a natural increase in complexity, and all levels are 100% solvable. Additionally, the game contains 10 undos to get you started on tackling tough levels, with optional undo packs available for purchase in the game.
