Hello! I've been working on a map for a landscape-oriented game project, and I wanted to know how to use it. It's an island in the middle of the ocean, so I don't know if tiles could work, seeing as they're square and the island has round edges and a section with a beach. The map is pretty big, and someone told me that I shouldn't use pictures bigger than 1000x1000px, so I divided the island in a bunch of pieces, which I don't now how to add to the project. Furthermore, I want to add an ocean I made in the background so the place actually looks like an island. Should that go in a different layer?
