I'm looking for options on how to get my game's installed on disk size on iOS smaller. Currently the best I've found is using tk2d atlases saved as PNGs, which results in 195MB. On Android, I get a 69MB apk (using atlases saved as Unity Textures.)
I was hoping that Unity 5.3 was going to compress your player data folder, but it looks like they've changed that - now you have to be using AssetBundles to get that compression. Is it feasible to use AssetBundles with tk2d? I'm also using 1x2x4x platforms, if that complicates things.
They claim to be adding support to compress the player data folder in the future...maybe I should wait for that?
