This is a SEGA Flashbeats inspired minigame for the Raspberry Pi Pico, Pimoroni Pico Unicorn Pack, and optionally something to make some sound.

You'll need Pimoroni's picounicorn module to run this. As of this writing, the easiest way is to flash their micropython .uf2 file for your Pico.
Push the center line to your opponent's end of the board to win.
Game files are in the src/ directory. Make sure you have the latest Pimoroni release of micropython for your board, then put all of the files in the src/ directory on to the device's root filesystem using one of Thonny, mpremote, ampy, mpfshell, or another tool of your choosing.
Files for a very basic case (no room for sound hardware) are included. The OpenSCAD file has a lot of "fudge" in the positioning where I've added a few tenths of a millimeter here and there. I should refactor and clean that up but I have not yet been motivated enough. The STL has been printed in PLA and tested with both a Pico W (with standard soldered headers) and a Pico H (with included debug header). I do not have a Pico WH for reference because they have not been released at the time of writing.
Right now the sounds are limited to chirps emitted by four PIO "voices". Each one goes to its own GPIO pin and I have them tied together as input to a passive piezo speaker. There is no "music" currently and the sounds are only emitted when a ball is launched and at the end of each game. Right now you're not missing much if you don't wire up sound hardware.
The font used here is 5x7.bdf, a public domain font by Dr Markus Kuhn that is included in the fonts-misc-misc bundle from x.org's font releases. I wrote a small script to use the bdfparser library to render this font to nested tuples of boolean values. This gained a tiny amount of performance over a more naiive method, but in the long run I probably need to move the buffer code to C.
