I want to be clarified here.
I am using Construct 3 (a game engine) to build game. After finish the game I can export game to HTML5 game + source code in .c3p file format (open in Construct 3 to edit game).
So I can sell the .c3p and HTML5 exported game right (in Code Canyon e.g) ?
Never sell assets of images for sure.
Br,
