CASTING SCALES

A roguelite about casting scales - the musical kind.

Your piano is your grimoire, and also your life bar: play chords and scales to cast spells, and every hit you take cracks the keys you play with.

I kept the game deliberately easy for the jam. The real goal is elsewhere: making you want to explore what the piano can do, and quietly teaching you real music along the way.

There are 13 elements to discover, spell shapes based on how you play (struck, rolled, held, descending...), elemental reactions to combine, and an endless mode. Check the Grimoire (Tab) as you learn, or the full wiki in the settings.

And when your run ends, the game hands you the melody you fought with, as a real .wav.

Controls

  Hold C = left, C# = up, D = down, E = right, in any low octave
