Hi, I whipped up this daily piano challenge game after noticing my partner struggling to play a tune by ear. She could hum the tune, but was struggling with recognizing whether the next note would be higher or lower than the previous. That gave me the idea of KeyByKey. A simple Wordle-style daily challenge game, where you are given a tune to play back by ear. There's no limit to the number of attempts, but after successfully completing the challenge it will show how you compare to other players. Still ironing out some bugs. Let me know what you think!
