A Tetris example project needs to draw 200 board cells and scan rows for a full line. Neither is expressible without iteration, so the node system gets a Repeat node plus the missing text side: Substring, Find text and To number. The interpreter drops its data cache once per round -- otherwise every round would recompute with the first round's values. Object by name takes its name as an input now, not just as a setting; addressing "c" + index is impossible otherwise. An unconnected input reads the stored setting, so saved projects are untouched. The board itself is a 200-character text, "." for empty. That makes both operations of Tetris a single expression instead of a loop, and each frame attempts exactly one move -- rotate beats sideways beats fall -- so the fit check exists once in the whole graph.
