CaveRibbon (SFCave Remake)
Hi HN! I made this project to indulge in some nostalgia for the Palm OS era. One of the hardest technical problems was fitting an entire replay’s worth of state into the URL fragment so games could be shared. I wrote up some of the details here: https://memalign.github.io/p/caveribbon.html
In plain words
CaveRibbon is a remake of SFCave, the classic Palm OS game, built as a web browser experience. It recreates the nostalgic gameplay of navigating through an obstacle course in a narrow cave. A notable technical feature allows players to share complete game replays by encoding the entire game state into the URL, enabling others to watch and replay specific matches. The project appeals to retro gaming enthusiasts and developers interested in efficient state compression techniques.
