The game often hints that the available block space is limited, or simply that efficiency is the goal, forcing the player to think algorithmically.

Level 9 often encourages (or requires) the use of "Functions" (depending on the specific version of the game and previous levels unlocked). Even without a dedicated function block, the logic requires the player to mentally abstract a set of movements. Instead of thinking, "Move, turn, move, turn, move, turn, move, turn, then move big distance," the player learns to think: "Draw Square, Move Over." This shift from line-by-line instructions to higher-level commands is a vital step in software development. One loop is never enough

She pressed Run .

This teaches the player that a single loop handles a repetitive task (drawing one square), but to repeat that task itself, you need a structural hierarchy.
