 If you have exit scene
 - You must create layer "exit". The layer have cases where the gamer can switch to the next scene.
 - In layer properties, you must add "exitSceneUrl" property. It represents a url map of the next scene For exemple : `/<map folder>/<map>.json`. Be careful, if you want that the next map will be correctly loaded, you must check that the map files are in folder  `back/src/Assets/Maps/<your map folder>`. The files will be accessible by url `<HOST>/map/files/<your map folder>/...`.
-
+- If you want to have multi exit, you can create each layer with name "exit". Each layer has key `exitSceneUrl` and have tiles what represent exit from another scene.
