The idea is good, but I think you should make easier to find the packages and I don't really know what the tools that you find on the map are for. You could make indicators of where the collectables are (like arrows or little animations on the minimap). You could also put a pop-up when you find for first time something that says you what does it do. When you change from the player to the drone and viceversa, if the player had a weapon, it doesn't fire anymore, could you fix that?
