Tower of Harmony is a short music-based puzzle made with HaxePunk. It takes inspiration from Loom, but while Loom used melodies as spells, in this game it's playing chords that causes effect. I asked a friend to draw sprites for it, so this is a team effort.
The controls are introduced in the game but for the record:
WASD/Arrows: movement R: Restart the level 1-8: select notes for playing Space: play the selected notes
