I've bought PICO-8 with the thought that it would be a neat way to learn coding and make small pixely games, but so far I can't get used to the language and workflow of Pico. I've tried deciphering other people's cartridges, but some things just make no sense. Is there anything I can do to learn Pico?

Hey guys, I thought PICO-8 could be a fun way to learn programming and do pixel art, so I bought the tool, but can't wrap my mind around Lua yet. What are some other ways to learn the code commands and their possible interactions apart from the Pico Zine? I also tried studying people's games here, but they seem overwhelming for now.
Cheers.
