I've installed and played "Ice Age Adventure". I played for some time and now I want to reset the game. I uninstalled it and re-installed it, but I get the same game progress. I can I restart the game from the beginning?
Usually there's an option to wipe save game data on uninstall but failing that, just find the folder on your computer containing the save games or in your case, whatever file records the progress. Once there's nothing on the computer, it should start from a fresh game after a re-install. Sometimes the information can be in two places- I think I found missing KOTOR (Star Wars: Knights of the Old Republic) games somewhere in the AppData folder when I was trying to mod them through a save editor.
But be careful if you need to remove files from the latter and check first they are game files and not anything critical.
Try deleting your temporary files. As for searching better, search from your main HDD for the game by title to see what files crop up and where they are all situated. This isn't a game where you use an online account for it, is it?
