It mentions a file called puzzle.lua. I'm running the latest version of playdate os version 3.0.3. and my playdate is almost full but I tried uninstalling some games so I had 400mb available and I still couldn't get the game to launch.
I just uploaded version 1.03 to Itch, which should hopefully fix this issue (possibly at the cost of slightly longer loading time when booting the game).
I also submitted this update to the Catalog, which should become available once Panic has reviewed and published it.
Could you let me know if this fixed your issue? Thanks!
