Thank you, I spent a lot of time making it resemble the arcade game, and I am also a "GnG veteran", so replicating that feeling was my priority, even though it is just a demo. I am well aware that some small details are still missing, such as what you mentioned about moving forward and shooting, and I have partially implemented something similar when you are close to the end-of-level boss. From a distance, there is a certain number of shots you can fire, while up close, that number increases. Other little things are missing, but at a certain point, I had to stop and be satisfied.
