i dont recommend extracting game files using es file explorer as it cannot extract all folder, i recommend rar apps, check game folder game size on rar app then phone memory size must have more than game size because if you decrypt, it increased a little bit just like compress rar files, if failed try restart phone and last attempt if not work is by download completed game save file, extract and copy or cut save folder and put it on your game folder name/www/save, usually it failed to decrypt because phone has low memory size, so i recommend you must have 1 gb on phone storage because this game zip file is 200mb and if you decrypt it, it might take 250mb,300mb or 400mb depend on game compression rates, if you always watch youtube or use any browser just go to phone setting/ storage go to installled apps and delete cache, or you can install any clear all cache apps on play store
