I have a project of a game that I want to share with my friends, is there any way to put it in a link that only those who have can see the project?
for Construct 2 google drive and share the link of the project, they would need to have C2 installed though to run the project. if you mean play the game, u can export a html5 version uploaded to some website and they access the website location and play the current uploaded version, if they are on wifi u might need to look at testing over wifi on C2 documentation, there was something about that years back. i can't see another way for it. for C3 you can copy that link directly from C3 menu.
