The files look encoded/encrypted in some manner so not much can be done without more info.

Edit: I downloaded the APK of the game and looked at the files. I could find the files you linked in your above post to that APK. However the APK did reveal that it uses Unity so you can check out the new Unity Asset Explorer topic and see if that helps any.

Encryption is AES/256/CBC for all files (Byte, Pb, Db). You can found DecryptWorker and TextureDecryptWorker in Bleach.Common.ResourceManagerBridge

Perhaps the key is in main library > libmain.so or something like that. Or as encryption key used md5 file hash.
