Click the boss and gather money... but if it gets mad at you, you may have to fight it. In the case of this happening, do NOT let it touch you. When it gets tired, click it as much as humanly possible in the timeframe of 3 seconds. (the amount of time before it regains it's strength) If you are able to bring it's health below 0, then smush it onto the ground by clicking it more. This will finally get rid of the boss. Oh, and whatever you do, do not put the cursor outside of the screen. This will stop the game and make you have to restart. This feature was added just for you cheaters out there ;)
This is just a little project I decided to do in my spare time. It definitely isn't perfect, (It may have a few bugs) but I might update it every once in a while.
