Why is the Cordova export so much bigger?

It is you who has to know your game, check the size of the folders, and check if it is the music or the images. Use the web format, and replace your sound files.

I don't think you get it. THE SAME PROJECT, UNCHANGED FROM C2, is ending up twice as big when compiled in C3.

This is surprising as C3 should export similar files to C2. Try looking through the exported files for any significant discrepancy. Which files exactly are new or larger?

It's not unheard of for third-party software like browser extensions or antivirus tries to be "helpful" and add a bunch of extra content, so it might not actually be Construct.

It is impossible for the "data" to double in size in your game, so it must be the images or the audio files. You just have to look at it in the cordova export.
