Aviva Creative Swap

I suggest you play on mobile it should work with any device without any installations.

(Sorry that there is no IOS app. I would need to buy a MacBook and then pay for licensing)
Controls:

Mobile -  Tap the notes as they enter  the area under Ieva

Pc - Use the Left, Down, and Right Arrow keys when the note enters the area under Ieva. The left arrow is for notes on the left, the down is for the ones in the center, and the right is for the ones on the right. You can also use your mouse to click on the notes if you feel that's easier.
