So I felt really split here.
Good - The art and effects and theme are consistent and look fantastic. You guys made a great looking game with a very consistent and pleasing aesthetic. Maybe the best I've seen so far in everything I've looked at this jam. Additionally, the music from DOS-88 is great, I love it.
Could Use Work - The controls and just gameplay in general were not super clear. Once I did start to get and understand what I was doing, it turns out it was just really simple and not all that fun. I also managed to just fly out of the map both horizontally and vertically and when I did stay on the map, flying the ship and hitting stuff with my guns was kind of frustrating. Would also be good to add some sound effects (as long as it doesn't interfere with the sweet music).
I know time is limited in a jam so I super hope you keep iterating on this afterward because it seems like a great start that you put a lot of effort into.
