I have come across a bug with the rendering one-off characters using a binary encoded string. If they binary encoded string ends in a nul \0 the character will not render.
For example:
"\^.⁸\0\0\0\0\0\0\0" doesn't work, the character will not render
"\^.\0\0\0\0\0\0\0⁸" does work and the character renders as expected; as does other combination tried as long as the last value isn't \0
None of this appears to be an issue if values are not string encoded first. Using a variable to store a binary value and using it to render a one-off character works in a cart regardless if there is a \0 at the end.
Doing this on the Pico-8 command line:
didn't work
print("\^."..chr(255)..chr(0)..chr(0)..chr(0)..chr(0)..chr(0)..chr(0)..chr(0))
worked
print("\^."..chr(255)..chr(0)..chr(0)..chr(0)..chr(0)..chr(0)..chr(0)..chr(1))
This isn't an issue when using hex values e.g.:("\^:FF00000000000000" always appear to work as expected)

Mines2
Back at it with a refactored version of the first Mines game. The goal here is learning and fun, and this project has been both of those for me.
Play
- Arrow keys to move around
- x to select tile
- z to set flag on tile
Features
- Minesweeper clone ('cuz there ain't enough of them)
- Level-progression game play
- Game field scrolls larger than game view to support super-big game fields
- Field continues indicator arrows
- Better performance at 30fps
- Intentional no mouse control to support handhelds
Hmm, that was shorter than I expected :). I wanted to refactor what I did in the first one and add levels. Which I did and they are working. It still ugly, but, well, okay. Could use some sound and music too 😉

Still working out
- some of the end game flag logic
- surrounding graphics
- levels
- sound affects

Hey so I built a clock. Just because :)
It actually turned out to be a pretty fun little project.
