Snake, played inside the program's own source code. The code is the board.
No sprites, no box-drawing characters, no pixels. When code-snake starts, it reads its own source file, minifies it, and lays it out as fully justified text filling an exact rectangle. The snake exists only as absence: words are pushed together and apart every frame so that a channel of whitespace moves through the live code. Eat, and the program's text makes room for you.
Most programs treat their source as an implementation detail, the thing you look at only when something breaks. Here the source is the material itself: the canvas, the playfield, and the collision geometry are all the same bytes that implement them. Edit the code and the board changes, because the board is the code.
This is not a quine. The program never reproduces itself; it consumes itself, reflowing its own text around the game state as you play.
