Suggestion about the uselessness of the zoom feature; It only works/shows once you have the upgrade within that view, zoom 2 would be satalites, 3 would be moon or meteors/comets, 4 and 5 would be the dyson sphere. Another thing is maybe add 'missions' or goals to reach for bonuses (like, for example, you would be able to set a destenation for your rockets/a rocket and do something to what you chose that could boost your satalites, clicks, ect.). Just to give the player something to do besides click constantly.
