As mentioned, if your game is not made with Construct 2 you're not in the correct website at all.
Also, "The last guardian" is a PS3/4 title that has been awaited for years now, and this name is copyrighted/reserved by Sony.
Moreover looking at "The last guardians" on google seems to refer a WOW server in the first search results.
So will your game be successful ? I doubt it. And if it is, you're facing possible copyright infringement lawsuit.
