I used app called Tiled. There you can add any ready spritesheet (png/jpg..), and build level from these blocks. I saw a tutorial in youtube, how to export map/level from Tiled app to Love2d framework. There was many info how to make different layers, integrate with player and other features. I used that approach only to get matrix of tile coordinates. To use that in my game, I was just using nested forloop for matrix and png file in game directory. Start with Tiled app, and then look the for the way to integrate your level/map to project. I bet there is articles/tutorial for any other game engine/framework.
Good luck!
