Duality

An Echo copies every move you make in its own bent way. Control both orbs together.

Mirror X in the first dimension, twisted further in later levels. Arena halves, one per orb, each with a far-end escape portal that orb must reach. Void Agents patrolling both halves. Moves safe for both orbs at once. Small pickups in two types on both sides. Streak multiplier.

Nothing starts until your first move. You have three hearts.

alessio_cagnin_, fascinated by quantum physics and parallel dimensions, made each level a small physics puzzle framed as survival. The Echo's own rules surfaced during AI brainstorming.
