In Guarantee, you start at the end of the level, with all of the enemies already killed. However, you must play the game in reverse to win. 

For the best experience, I recommend recording the game and viewing the video in reverse.

 The game fits the "Nothing can go wrong" theme because the game is already "won", meaning that the player did not lose.

Objectives:

-Un-kill all enemies by shooting them

-Return to the starting building at the top right

Controls:

Q and E: Switch weapons

Scroll Wheel: Zoom in or out

Right Mouse Button: Move camera

Mouse: Aim and fire

WASD: Move

Z: Explode everything (this was originally a debug feature, but it's fun, so I kept it)
