Back in early 2023, I posted the code & hardware plans for a modernized clone of Sokoban, an obscure but *really* fun logic-puzzle game from the 1980s. Unlike most of the other "retro nostalgia" pieces, the game holds its own today.

I handed it out to a bunch of friends. Few have heard of the game before; just as few could put it down once they started.
Unfortunately, because Sokoban is not exactly Pong, Space Invaders, or Snake, the project never garnered much attention from strangers. And keeping the project alive proved to be a chore because of post-COVID shortages. The MCU I relied on soon went out of stock. I redesigned for another chip... only for the OLED vendor to tell me they're discontinuing the display b/c *they* can't find the chips.
Anyway, I have a revised PCB and code for a new display ready to go, just need to test it IRL. And hey - have you considered a nice game of Sokoban?
