In 37 moves, free 8 birds. The bottom part of the grid which the birds have to reach is filled with ghosts. Fortunately enough, there’s enough space to match gifts and get a first move over those ghosts. Even if the birds are the objective, with 37 moves to go, we should make sure that the ghosts won’t hinder our progress.
As always, when birds are involved, careful not to stack them up over obstacles.
Focusing on one side and clearing all the ghosts from there will help out with the objective as some of the remaining birds will spawn from the sides. The protruding bits of the grid in both sides with the teleporters are still connected to the grid. Just remember to match some gifts there so the rest can flow diagonally.
