When you click the flag, there will be a POWER OFF switch. Click it to POWER ON. After that, press the D key. A warning will appear. Listen to the warning. After that, click PROCEED to get to a boss battle. The battle is VERY HARD! NOT FOR THE FEINT OF SORE CLICKERS!
Credit goes to the person who made the WARNING pic. I added areas to where you can click. Credit goes to the person who created the SONG that I used for the battle. If there is ANY bugs, or ANYTHING you want ME to add, let me know below. If I do it, it MIGHT be an EASTER EGG, or IN THE GAME ITSELF! 1/11/18: UPDATE! Added a very SECRET MINIGAME AREA! With a very SIC beat! (Link to song) https://www.youtube.com/watch?v=2lyTpMOjnVw
