Touch: Not supported - this is an explicitly keyboard-only game by the developer's own design · Keyboard: A, S, D, F to repeat the sequence; space bar for new game, Esc to reset
About:
A clean Simon-says memory game mapped to the home-row A/S/D/F keys. The game explicitly describes itself as a 'Keyboard-Only-Game (KOG)' in its own body copy and was never given touch controls, so it is correctly shipped here under the desktop-only tier. A legacy Google Analytics snippet was found in the source and removed before publishing. Keyboard input was confirmed genuinely correct by deliberately pressing a wrong key: the game produced a precise game-over message naming both the correct expected key and the key actually pressed.

Phone check: 2026-09-08: found and removed a legacy Google Analytics (_gaq/ga.js) snippet from index.html before publishing. Confirmed the game explicitly states it is keyboard-only in its own text, correctly reflected by the desktop-only platform tag. Verified keyboard input for real: started a new game with space, then deliberately pressed the wrong key during the sequence, producing an accurate game-over message naming both the correct expected key (d) and the key actually pressed (a) - proof the input is genuinely read and compared, not just accepted. A stale prefixfree.js reference from a raw GitHub URL is blocked by modern browser ORB protection but confirmed harmless - the page renders and functions correctly without it.
