Arrow keys to move the camera. Restart the project to apply a new size using the slider in the top left. This is a demonstration I made to experiment with zooming the camera, so players can see a much larger area when playing, which is something I am sure we have all wanted at some point. I am well aware that the elevators, vents, hazards, and doors are not present.
The graphics are from @KIKOKO_'s Robot Destructor. I do not exactly remember how much code I modified from the original project, because it was a while ago that I optimized most of the code, but I think it is safe to say that most of this code is based off of the original project.
