This borrows Tetris-shaped pieces but changes the goal: drag each piece so its key lines up with a caged animal's lock, and the cage springs open. It's less about clearing lines and more about matching shapes to a specific target on the board, which makes it feel closer to a fitting puzzle than a stacking one. Special blocks show up as you go that block or complicate a straightforward placement, so later boards need more planning than the early ones let on.
