+1 on this. Even as an adult I found other game authoring systems too complex to jump into and feel comfortable with (as a hobbyist). Pico-8 was the fastest, easiest "I'm thinking of something" to "I'm seeing something happen on screen" iterative development cycle and a joy to use. Plus, a great community of people willing to help on lexaloffle.com and especially Discord. Some great YouTube tutorials out there as well.
