Can i please ask how to delete it?
Hi! Of course!
1 - If you want to delete your savefiles: type "%appdata%" in your windows search bar. Go back one by clicking on the "AppData" folder in the path bar at the top. Then click on "LocalLow" and delete the "Mariarco Studio" folder if you want to delete every savefile. If you're looking to delete a specific pet go into the "Mariarco Studio" folder, then into the "DesktopPet" folder and find the name of the pet savefile you wish to delete.
2 - If you want to delete everything, delete your savefiles (see bulletpoint 1) and then delete the zipfile you downloaded to get the game!
