Through the furious mashing of your Q, F, A, and S keys, you beat the game. Unfortunately, you and up to three "friends" become stuck on a rock floating in the sky as the credits roll, having forgotten how to use the "town portal" spell. It's okay, though; you have a new sequence of keys to mash to test on your "friends" and possibly yourself.
In the sequel, you are stuck in a laboratory with a sad golem and up to three "friends" while badass party music plays as the credits roll. When the credits finish rolling, the golem may or may not have detonated from sadness, but you're kicked back to the main menu before you can find out.
In a completely different game, you have !!FUN!! by opening the circus and offering ridiculously expensive prepared meals to the clown-based welcoming committee. Your fortress of bearded drunk midgets might not survive, depending on a number of variables that may or may not matter.
