Hey! Played the game for a bit and I can say there is a lot of potential in the idea you are working with here. The game can feel a bit oppressive at times with weapons being somewhat scarce and drops being random, but I really think the idea can be polished into something really interesting.
On a minor note, the movement in the menu feels a bit clunky with the movement inside it being reserved to A and D, I miss being able to go down a row, but this is just a nitpick.
