QuantumS was developed by ACM Gamebuilders during 2007 and 2008, and was an entrant in the IGF Student Showcase competition. Timmy is a boy who has run away from home, and his wandering takes him to a ship where the rules of time don't always hold. Now, in order to escape from a ship full of unfriendly guards, Timmy must solve puzzles using time as a tool. Utilize previous selves and the fourth dimension to escape the ship!
This is a screenshot of the 3rd level in the game, demonstrating some of the gameplay mechanics such as past instances of yourself, guards, treasure chests, and door/switch puzzles.
