also maybe add like a system where your score is saved, and you gain points that you can use to permenantly increase your stats, to add a sense of progression and something to work towards. also i do like the idea of more perks, like more fire speed, natural regen, and maybe homing bullets, as a mythic sight option. as for more parts, i can think of a few, which would probably be as a new level of parts, called super, which would be very _very_ rare
