I made a level, a simple card game to test the Android Export Plugin. Hmmm the .Apk when it installs on android is about 5.MB. only frame lol.
Now I reduced the color and I got 3.3 not bad. But when I download games from the Google App Store they are normally about 5 to 3M.
I guess the best way is to optimize the images in Photoshop.
What are you guys doing to reduce file size?
