Too much space on the device

Hi guys,
I have a game that already released on App Store and the size is around 77 MB.
In this game i support iPhone 3GS and above resolution including iPad retina (universal app).
So, basically i have three type of image resolution (512, 1024, 2048) and switch them according to the device resolution.
After a few days, i have a lot of complain that my game taking too much space in the device.
I checked it by myself under settings > general > usage and it seems true my game usage is taking 440 MB on the device.

Anyone can help shed me some light here on how to decrease the size on the device?
I think i missed something here (about texture most likely)

Thank you very much :slight_smile:

Well, are your texture and audio assets compressed? That’d be my first port of call.

If the App Store package is only 77mb that implies that your content is pretty compressible, so take advantage of that and see what you can squeeze.

@tier, maximize the use of textures and gui graphics in 2 power if possible, for example your all textures that you use for game objects should be 32x32, 64x64, 128x128, 256x256, 512x512, 1024x1024. unity compresses it automatically when we deploy application.
