pvananh2805/ARTILLERY-SIM-GAME ? reverse-engineered prompt

Build me a standalone 2D artillery simulator game where I can place a target on a map, aim a heavy turret, and fire shells with realistic physics. I want the shot to account for distance, angle, gravity, wind, altitude, and drag, and I want the game to show both the predicted arc and the actual impact so I can adjust my aim like a real artillery observer.

Please make the map zoomable and pannable, with range and bearing tools, grid lines, and a simple target marker. The turret should feel heavy, with slow traverse and elevation, plus a faster mode and a fine adjustment mode. Add a simple loading and firing sequence too, so I have to load the charge, ram the shell, close the breech, arm it, and then fire.

It would be great to have an auto aim button that solves the firing angle for me, plus a debug view with telemetry and a trajectory graph. If you need to, look up current docs online for any libraries or setup details.
