We are a group of Northeastern seniors working on a year long capstone project. Our group is comprised of four programmers and one artist. For the project, we have to come up with a game concept and implement it all the way to a playable demo. In addition, we are conducting user testing in order to facilitate a productive iterative process. The game we are working on is called Time Sink. It is a 2D shooter with a strong emphasis on puzzle and platforming elements. The main draw from a gameplay perspective is that there will be time manipulation mechanics. From a narrative perspective, the game revolves around the concept of time travel. As a by-product of creating this game, we will also be releasing an open source version of the engine we have written.
