Hello there, I am wondering : is there any way to collaborate with someone so that he can still build levels (spawning tiles and monsters), actually run the game to test it but without sharing all the programming I have done in my project. I just had a bad experience... I am not sure there is a way. The method does not have to perfect, I can focus on key assets as the objective so far is to iterate quickly on the levels, try, test, retry. Even if we have to properly rebuild the levels, once they are ok, at the end with more details and care. I thought creating an extension including all my resources migth be an option ? Programming my own editor sounds overkill. Any hint is very much appreciated. M.
