I managed to decrypt the assets file from the app directory, but the sounds seem to be encrypted (.fsb filetype)
Here's a screenshot of all the sounds from the .assets file, it'd be nice to have some of them as a ringtone. If someone could help decrypt them and convert them to .m4a or .mp3 that would be amazing. Thanks!

I had to extract the main file (sharedassets0.assets.resS) using Unity Studio, then I extracted the .fsb with FSBEXT and those were the files I got. When I selected the fsb file, I got the following message:
"probably the file uses encryption, insert the needed keyword. Type ? for viewing the hex dump of the first 176 bytes of the file because it's possible to see part of the plain-text password in the encrypted file!"
Here are the untouched files: https://files.fm/u/dmzsd36v
If anyone can decrypt the music sound fx, I will happily send a little tip via PayPal

Thanks
