Just got done watching this, thanks for the video it's very useful.
I can see I did a poor job of communicating some important things and maybe that's why some people are finding it harder than others. I'll make sure gun pickups and supply crates are more noticeable. Rags tells you that the chieftain's camp is the harder of the two available levels but In retrospect it's obvious that if I unlock two levels at once they should be equally challenging, or at least I should add some difficulty indicator on the map screen.
In my game's defense I think playing it with a timer trying to rush to the boss is counterproductive since a lot of resources are rewards for exploring but I agree that at the very least pistol and shotgun ammo should always be plentiful. I'll be more careful with balance going forward.
Thanks again for streaming my game! It'll be more fun next time.
