hey, congrats on finishing your game!! the only problem is that i dont really see the duality in this (the theme) and i dont really get what you have to do but over all keep it up!!
My idea was narrative duality. There are two sides to war, and each side sees themselves as the hero. If you played until the second half (which triggers after you die) then you play as a doctor on the opposing side. I guess that wasn't so obvious tho 😅
