About Catris
Catris is a arcade game by Thiago Romão Barcala and Markus Mroß, submitted to the js13kGames 2025 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.
This entry is part of our catalogue because it represents the spirit of the size-limited game jam. Play it on the official js13k showcase to see what fits in 13KB.
How to Play
Most js13kGames entries use keyboard or mouse controls. Click through to the official js13kGames page for Catris to see the in-game instructions.
Generally: arrow keys or WASD for movement, mouse for point-and-click titles, and space for primary actions.
