Velvet Echo · The Hidden Choir
An original cozy signed-sum listening puzzle: invite a few illustrated woodland voices whose six bell signatures add to hidden target readings. Opposite changes cancel. Ten uniquely solvable choirs, live previews, capacity limits, exact nudges, undo, keyboard/touch controls, optional sound and device-local listening seals. Eight original GPT-generated sprites are the playable cards and choir. Original MIT game inspired by October2026 sparse-feature interpretation research; GitHub is research reference only, no upstream code, models, datasets or assets reused.
