I made another thread asking why the Crosswalk file was so huge, even for a very simple game.
What I don't understand is how you get big file size (15MB), before doing the deployment. Do you export the HTML5 files out of Construct2?
During that step, you should get low file size, the problem is after the deployment with Crosswalk. Or maybe your game is a big one, and that is why you get 15MB.
But, if you get like 15MB before crosswalk, then after crosswalk how much do you get? Like 200MB?
