Fruit Ninja: Math Master (*.OBB/*.RKV)

[LolHacksRule]

I'm trying to extract Fruit Ninja: Math Master. On Android, a small portion of the game data is not packaged, but on iOS or in general, everything is packed in the OBB (Android)/RKV (iOS). On Android, the OBB is not a standard zip and the content in the file is zlib compressed, which makes it easy to at least get the assets without proper names. On iOS, the file I think is deflate compressed. Can someone make a script to properly extract the game data? There appears to be interesting content in the game. I'll upload samples aside from the OBB patch soon.

Transfer of the main game data will expire in three days from now.
