Only the current version so far — new entries appear as the game ships updates.
A moving lamp keeps casting a shifting umbra. Draw shadow walls with your finger to stop shade beasts from breaking the rim. Each blocked beast scores a point, and spawns grow faster. Grab Shadow Harden to keep walls longer, or Instant Wall to drop a long barrier at once. Endless mode with no fixed stage — if a beast escapes the contour, the run ends.
