The board is a list of 200 numbers now instead of 200 characters, so a cell is
Item at and a landing is Set item instead of seven nodes of string surgery.
The bigger change is that the one 219-node graph is gone. Each step of a frame is
a behavior of its own - Spawn piece, Next move, Fits, Draw piece, Lock piece,
Clear lines, Show lines, Draw board, plus Piece cell for where one of the four
cells of a piece sits. None of them holds state: what they need arrives through
their inputs, every answer leaves through their outputs. That is what lets Fits
answer for turning, moving and falling alike, and Piece cell serve the fit test,
the drawing and the landing instead of being the same twenty nodes three times.
Tetris itself is down to 84 nodes and only says in which order the steps run and
which variable each answer lands in. The smoke test holds it to that: it fails if
a loop or a list access reappears in the master graph.

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.
