In 30 moves, light up all 4 pumpkins…using striped gifts. Although not explicitly stated in the objective, from even the first glance we can tell what the deal is. Thankfully, to make matters easier, there are two teleporters in the grid, which allow a certain foreknowledge of the gifts in these moving columns.
Therefore, the main objective is this: make horizontal striped gifts, and guide them through the columns with the teleporters. Line them up with the pumpkins on the other side of the stage, and match up these striped gifts to light up the pumpkins. In case lining them up proves to be an issue, remember that a gift bag with a striped gift combo sends out multiple rows of rockets at a time.
Once enough obstacles have been cleared, you can ignore that last column on the right and focus on getting your striped gifts in place.
