SWEET!
Here's a tip to earn a shitload of money: First, make enough money to buy the gravity shifter. Then, move the gravity shifter over to a wall on the side of the room. Now, switch to Tickle. Making sure the Buddy Icon is stuck on the wall because of the gravity shifter, start tickling him. After you've started, continue holding down the mouse button, and move it off the game page. The Buddy Icon will continue to be tickled, giving you about $200 every minute. Come back in about ten minutes, and see how much money you have. I'm currently at $3,400 and rising.
