Yes, as in Rules, this particular jam is only about using Defold to make a game or an asset ;) You can though mix multiple tools, I know about situations, where people used e.g. both Godot and Defold to make an online game, one for server, one for client :D
Hello I have a question does it have to be a mobile game or a desktop game and how should I do it so that you know that it was created with defold. If there is something wrong in the text, sorry in advance, I speak German as my native language.
