Thank you so much! The camera following ranged attacks was definitely on our todo list, but we ran out of time! :(
About the difficulty, you really need to keep recruiting people in every level in order to have a team capable of taking on the next! If you fail to recruit at least a couple of people in each level, I would recommend retrying that level, even if you've cleared it. You're pretty much guaranteed to get rekt on levels 5-7 if you haven't built a solid team by then. There is however an exploit that you can use to save yourself If you haven't built a strong enough team and you got far: If you recruit someone and then you end up failing that level, you still get to use the recruited person in your retry.
