Did some reading, reoriented a little with drawing, played some games.
I found a tutorial on writing music for the PICO-8, followed along, and I think the result is passable. I don't know if it makes sense as, like, background music for tic-tac-toe, but one step at a time. There is way more depth to the PICO-8 composition tools than I realized at first.
Too bad I don't seem to have much to talk about regarding today, but I'm happy with how things went.
Moving forward, I'm going to try to have more focus. Take a break from the PICO-8 stuff, except maybe to watch the tutorial series, then come back to it later. Probably stay away from Minecraft for the near future.
