Picnic Basket Defense

You and your friend planned a romantic picnic in the park. Everything was going well until you suddenly realized you are not alone: ants are coming from all directions to take your precious food. Of course, you will not allow them to do that! Optimize the use of the resources available in your basket to stop the insatiable insects. Place bottles of mustard, ketchup, and other items in the ants' path. Use the earned points to buy new devices. Good luck!
