@JeffGrigg Why would you want a dedicated hardware for any game? Pac-Man handhelds are selling like hot cakes on Amazon.
Single-purpose devices are just nice. You can also give them to kids and not worry they're gonna be watching weird auto-generated videos on YouTube all night.
@ori The only point I'm making is that if you put a hardware project described as a "retro-modern Sokoban clone" on the internet, no one will come looking for it 
@ori Like, these gadgets are really well-done and I had a hard time *handing two dozen out out for free*. And almost all my friends are nerds.
@ori Of course it's obscure. Ask an average online person about what retro games they're aware of. Many will mention Pac-Man, Mario, Tetris. Many geeks know Space Invaders and Pong. Approximately no one will mention Sokoban, or have any idea what you're talking about if you bring it up.
@todb The problem with the original game is that, much like most other computer titles of the era, it was supposed to be very, very hard by today's standards.
I put quite a bit of effort to rebalance it and gently ramp up the difficulty. There is an extended intro section made out of Sokoban Jr levels, for example:

(These are playable via JS, by the way.)
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 had heard of the game before; just as few could put it down once they started.
Unfortunately, because Sokoban is not exactly Pac-Man, Space Invaders, or Tetris, 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?
Youngsters find it hard to believe, but before Apple introduced the first cell phone, you had to carry one of these bad boys with you if you wanted to stay in touch with friends
Of course, no C tutorial is complete without an explanation of basic loops:
