Tetris monochrome

Tetris monochrome is a puzzle game by John Swana, submitted to the js13kGames 2020 competition. Like every js13k entry, it was built from scratch in under 13 kilobytes — code, art, audio and all — which is an extraordinary constraint that forces clever, focused design. It was recognised in the 2020 competition.

This entry is part of our catalogue because it represents the spirit of the size-limited game jam: complete, playable experiences distilled to their essence. Play it on the official js13k showcase to see what fits in 13KB. (This is a factual placeholder — a full review will follow.)

Most js13kGames entries use keyboard or mouse controls. Click through to the official js13kGames page for Tetris monochrome to see the in-game instructions, as controls vary per entry.

Generally: arrow keys or WASD for movement, mouse for point-and-click titles, and space for primary actions. Many entries display their controls on a title screen. (This is a factual placeholder — specific controls will be documented in the full guide.)
