Hello. So I'm working on a game that is the learning countries of world, right now I'm collecting the graphic assets of the game, and when you select a continent there will be a scroll menu to select the countries, when a country is selected it's gonna be highlighted on the continent's map then on enter the country's map will be shown and some info, the thing is I need images maps for all the countries in the world, if anyone has an idea on what is the best way to do it instead of using a lot of images, if there is an online tool to crop images in an easy way, or like an easy implementation and assets for that, or even an open source maybe for the maps of all the countries? idk please some help here!!
-Thanks
