Window

Window is an option in Escaping the Prison and Completing the Mission. It results both in a fail and success.

Escaping the Prison
During the "Sneaky Escapist" pathway, if Henry decides to use the File, he can use it on the bars of his cell window. However, he forgets his cell is not on ground level, and he falls out the prison, which results in a fail.

Trivia

 * PuffballsUnited, the creator of the game, used the window fail in EtP for testing fails.

Completing the Mission
During the "Cleaned 'em Out" pathway, when Henry is stowing away on board the Toppat Train, he can hop out the window and onto the roof to avoid detection. This gets him out of trouble for a moment, but then the train approaches a tunnel. In this second choice screen, Henry can try to board the train again through the same window, but now the window is closed and Henry smashes against the glass, resulting in a fail.
