Press the b key first. Then press the green flag, a apple will show up! Click the space bar key, another apple will show up! Click the up arrow on the bottom on the right, another apple will show! Same as the up key, press the down key, another apple, and the backdrop will change!
I got 4 apples, then hid them, then press the proper keys to show them like I told you. The backdrop will change when you press the last proper key.
