You can play TETRIS with a MIDI controller or a computer keyboard.
Originally made to work with Teenage Engineering's OP-Z.

First. Set up your OP-Z so that it's sending MIDI.
I use the iOS app. Otherwise refer to Teenage Engineering's documentation.

Midi Not Supported
Unfortunately, the Web Midi API is not supported for all browsers.
Here's the compatibility list.
Supported at the time of publishing:
- Chrome <- what I tested
- Edge
- Opera
I tried to add support using this polyfill, but was not successful. I welcome anyone to try getting it to work.
