The popularity of Wordle's emoji results made me think 8 bit games might be playable on Twitter, so I answered the question nobody was asking: Is this playable as a crowd-controlled tick-based game? The answer is, sort of!
In a few days, I prototyped this at full speed in an ObservableHQ notebook (which is now a playable companion game) and then turned the game into a GitHub Action that reads in a save file, tallies up replies for directions, updates the game board, tweets and then commits the save file to its own branch.
The first couple users wanted to do moves that weren't supported and broke the game, so I added features and debugged between tweets. I added separate dark and light modes at set times of day (unfortunately based on U.S. time zones). And I've been testing lengths of time between tweets (30 minutes feels slow if you're waiting for a move, but allows for users to follow the bot without taking over their timeline and to come back to it at intervals).
