Chunky Melon Haul

Grab fresh watermelons from the field and toss them onto the moving truck. You need to match the exact type of melon the driver needs, but the truck bed fills up fast. If you pile too many mismatched ones, there will be no room left for the good ones.
New orders keep popping up, and the vehicle waits for no one. You must quickly decide which melons to keep and which to leave behind. Time your throws right to fill the quota and send the truck on its way before the next batch arrives.
