Perhaps Portal of the Orange Box fame?


After drawing Chell, I realized she was quite tall, but I'm still happy. The game would be more like an adventure puzzle, arrows controlling movement/look, A as jump, B as shoot/interact, and select changes portal "color". The Aperture Science logo changes from dark to light, signifying what color portal, either light or dark, the gun will shot.
