Very nostalgic for the good old days (of boomer shooters, not war). The audio and art both helped push that feeling.
The reload mechanic was clever, but there was only one section that it felt like I was under pressure to rush it mid fight - perhaps this is good that it wasn't a constant and within the jam timeframe maybe not enough length to get a nice rhythm of calm->frantic->calm going, so not a huge criticism.
Good job on the entry. I hope armydillo gets the support back home that he needs :(
