I Wanna Be The Guy: The Movie: The Game (IWBTG) is a freeware video game first released in October 2007 by Michael "Kayin" O'Reilly. Like many traditional games that I Wanna Be the Guy parodies, the game's plot is straightforward and does not heavily impact gameplay. The player controls "The Kid", who is on a mission to become "The Guy". The entirety of the plot is given in a message during the opening credits, a parody of bad Japanese translations and broken English in early Nintendo Entertainment System games.
IWBTG is most famous for its difficulty. Most of the landscape is engineered specifically to kill the player. Alongside a traditional range of recognizable dangers, such as spikes and pits, there are many less obvious threats as well, most of which are all but impossible to avoid without either previous knowledge or trial and error (such as Tetris pieces and "Delicious Fruit", which can fall downwards, upwards, or sideways). "The Kid" always dies with a single hit, at which point he explodes into a mass of blood. Although each death results in a "Game Over", the player is allowed an infinite number of attempts. From the starting screen, there are four different ways to progress; all of them ultimately lead to the same warp screen which returns to the first screen. Thus, to complete the game, the first six bosses along each path must be defeated before the warp screen will allow the player to access the final area.
The game has four difficulty settings: "Medium", "Hard", "Very Hard" and "Impossible", with "Hard" considered to be the "normal difficulty". The main difference between difficulty settings is the number of save points available throughout the game, from 62, 41, 22 to only one (which is only available for one frame). Also, while playing on Medium mode, The Kid's hair has a pink bow in it, and any save points exclusive to Medium difficulty are labeled "WUSS" instead of "SAVE".
