How to play

Each invader falls in a lane above one piano key. Tap or click that key to fire, so you learn where every note lives on the keyboard.
With Music set to Songs, each wave is a well-known tune such as Twinkle, Twinkle, Little Star or Ode to Joy, and invaders arrive in its rhythm. Shoot them in order to play the melody. Choose Random notes for a free-for-all.
Choose a one, two or three octave keyboard. Wider keyboards spread the invaders across more keys.
Press P or Esc to pause.
With a MIDI keyboard connected, a key in any octave shoots the matching note.
Hitting invaders early scores more, and every five hits in a row raise the multiplier. A key with no invader above it breaks the streak.
You have three lives. An invader that reaches the ground costs one.
Once the keys feel familiar, hide the note names on the invaders, then on the keys too.
