5a: layers to understanding programming

HECTORING PEP-TALK: YOU ARE WISER NOW. Let's delve a little deeper into your BASIC PROBLEM SOLVING techniques

UNDERSTANDING comes in 3 layers:

0th level, THE FOUNDATIONS: what even is the realm of possibility?

1st level, GROUND FLOOR: awareness of the things in PICO-8, like functions and the tools that are available

NEXT LEVEL: using the functions in different, but common ways to solve common problems, and also using these foundations and awareness to invent new behaviors in the game engine.
