The main point of the game is to show 4 foods and then randomly show 4 sprites, 3 of which were not shown, one of which was shown, these 4 randomly each set in 1 of 4 positions. So you basically have to remember which was shown, go to it, and if you were right you get a point and it goes again. I am very new to coding and need help past this block here.
