Picnic , released in 1982, is an action-packed adventure game where you find yourself enjoying a picnic when suddenly a swarm of flies arrives! You control a fly swatter at the bottom of the screen; your goal in this game is to protect your hamburgers (located on the left and right bottom of the screen) from the attacking flies.
When a fly is close enough, it will stick out its tongue to eat the food. If you can swat the fly right when it has its tongue out, it will be knocked out and fall into your fly trap. When all of the flies have been knocked into the trap, you will then need to face a large super fly before the level is complete (be careful, it can eat your food fast!)
The gameplay involves timing your swats perfectly to catch the flies and protect your hamburgers. As you progress through levels, the number of flies and their speed increase, making it more challenging to win.
