Show HN: ChordsCrush, a free musical chord training game

I've always wanted to practice playing piano chords on my computer, so I built this simple game that gives you a random chord to play.

The game supports input from a computer keyboard, a mouse, a touchscreen, and even a MIDI keyboard.

There is a training mode that will highlight the notes to play.

You can also adjust the difficulty, the oscillator type, and the root note of the generated chord.

Built with React/TypeScript.
