The Gateshead Engine

"The Gateshead Engine" is a single-player game set in a steam-powered Victorian England, where you play as an engineer building a mecha for a powerful patron. The game utilizes a diary system to chronicle your progress, thoughts, and fears as you work on the complex machine. It can be played in one sitting or over several nights, and is a hack of the game "Alone Among the Stars" by Takuma Okada.
