there are two points in that tutorial that arent true i think
[quote:3ay53n1v]- Don't bother trying to run the exported image files through other compression tools or services. Construct 2 is probably already doing a very good job."
try running the exported images trough pictureslash.com , i ALWAYS get improvements with that, expecially if i have some big images with much details and transparency then it saves between 30-50% of download size compared to the brute png compression of construct2.
[quote:3ay53n1v]- Don't try to manually delete audio files before exporting. Construct 2 automatically removes any that are definitely not needed on export.
i just exported a game where i imported like 20 sound effects and only used three and every single sound file is also in the export folder
