Echo Protocol

Echo Protocol is a free platformer made with AI by @rudi09, and you can play it right here in your browser.

Enter a dark sci-fi facility as Subject 404 in Echo Protocol, a 2D puzzle platformer built around recording and deploying temporal echoes. Your first objective is clear: leave an echo on a floor switch and make your way through the chamber.

Jump between platforms, navigate a vertical sync lock, and head for the sector exit. The interface provides four temporal memory slots, a record-echo command, undo, and controls for movement, jumping, and dashing.

Mint-green highlights cut through steel-blue machinery, pixel-art details, and a scanlined display. A towering E-marked device dominates the room while the status panel identifies CHRONOS as hostile.
