Well First of all download the cache file ( https://low7.platinmods.com/get_fil...sWkM1eWRTNTZhWEE9fDE2NzE3MTkxMTR8MzB8MTQ4Ng== ) then extract it and after you've extracted it there's a folder named com.aboutgames.com.unity.idlerpg.mobile2D, move it to android/data and replace the existing file then that's pretty much it (delete the txt. File cuz it won't come in hand).
Well pardon my idiocracy as I had not known such thing as no links was a thing, therefor you just need to visit the website that pops up when you open the game and download it there.
