Kindle Fire Backup + System Cache Cleaner Needed

[DJ Panda]

Hey everyone! Since its release I have been a Temple Run fanatic. Currently I am so far in the game that I have to unlock 1 item and finish 1 quest. (Both are almost done) Taking years to complete I am worried that my Fire will die eventually and do not want to lose my save game. Kindle's app store is pretty limited. I use ES File Explorer to copy my app folder into somewhere on the Kindle's SD and then transferring that to my computer and other cloud storages. With so much stuff unlocked I have to periodically clean the cache about every other week. However, the default cache cleaner for Kindle won't let the game fresh install the files it needs to run properly. Currently use this app https://www.amazon.com/Cheetah-Mobi...e=UTF8&qid=1487197570&sr=1-5&keywords=Cleaner (CCleaner doesn't work well either.) The app seems to work well but at the same time gives all these fishy popups.

Anyone have any suggestions for other ways on backing up my game data/ clean the cache?

Thanks!
