If i upload a file of my game for problem discussion is there any chance that someone will take those files and make a his own game out of it?
The idea is to not give us your full project, but just minimal examples to work with*.
I am not aware of any case of stolen project, of course the theory and logics that you share could be “assimilated” 
Not sure about graphics, and resources in general… I’m not a lawyer, I would upload just the necessaries, or sketches 
*We (at least I) are not personal helpers for specific projects, I will not read all the code and logic around a full project of hundreds of lines to get what is going wrong, I want to help with the software workflow, the GD logic and some theory about game development focused on GD possibilities
