Oh man, this takes me back! In my college days, I designed a pitch for an action game based on Vietnam. It started off as a direct adaptation, but the period was so sad that I just couldn't recreate it as realistically as I was told to, so I made it into a Game-Boy-style run-&-gun instead to make it a bit less haunting. Got top marks across the board for it! Sadly, I lost the files for it over 10 years ago now; the project leaders didn't give us much time or space to save anything beyond the deadline.
Your art looks almost exactly like my pitch! ❤️
