The Game's Story

Inside a music box lives a ballerina, who, by spinning, keeps the music alive. However, an army of mechanical musical notes threatens to end her. These notes, which once danced to the same rhythm as the ballerina and were her faithful defenders, have been corrupted by greed and fatigue from always having to stay in tune with her. Now they march in rebellion to annihilate her.

But the ballerina is not alone. A group of instruments rises to her defense, ready to do whatever it takes to allow their beloved ballerina to keep bringing the music box to life. They are prepared to take down any notes necessary to achieve this.

Meet Our Mechanic Notes

Quarter Note

Quarter

Watch out for this rail-riding ground enemy. It may not be the fastest, but it steadily advances, smashing into your towers and the ballerina with brute force.

Half Note

Half

This ground enemy moves a bit slower than the crotchet, but don't let its pace fool you — it packs a heavier punch. If it reaches your defenses, it will deal greater damage than you'd expect.

Quarter Rest

Quarter Rest

The only flying enemy in the game, this one glides along ceiling rails. It's not very durable and deals less damage than others, but attacks from a distance.

Special Enemies

Whole Note

Whole

Moves slowly along the rails, but its blows pack a serious punch. It's tougher to take down than most enemies out there.

Eighth Note

Eighth

Lightning fast, striking twice in a flash. You need to destroy both notes to defeat it. Take down one, and the other will rage, speeding up and hitting even harder.

Final Boss

G Musical Note

G - Treble Clef

This boss moves slowly along the tracks, usually accompanied by several enemies which it infects to steal their life and heal itself. It attacks by throwing acid droplets at the ballerina. If it reaches her, it will take her down with a single hit.
