Ok you seem to have an identical problem which is great as we could exchange solutions 
Another thing I’m struggling with is the connection between the scenes. Imagine a lot of different scenes connected as in a maze. Now the problem is Defold does not allow you to fetch resources dynamically (for what I understand) so you must identify every scene in a collection proxy. But for what I’ve read there is a limitation to the number of collection proxies you can create for one game object !
Are you in the same scenario ?
