Here we have to save 2 single snails in 20 moves or less. The entire grid is covered in obstacles, with a number of special gifts in Gift Traps all the way down the central column. Swipe the only two special gifts that are free, and clear the middle of the grid. Once gift circulation has been restored, make your way to the sides and free those snails. The more obstacles you destroy, the more opportunities for special gifts. Stack them up with each other and blast through most of the Blockers and Gift Traps. Should be simple and easy enough.
