itch.io

Hello! I need help with something. Please bare with me I have no clue how to run things so some things are very hard for me to do regarding computers, So I recently finished the game ! and after the whole ending it deletes itself(?) so I deleted the application (bc it wont let you continue after the goodbye letter), but soon after I realized I wanted to play again and try actually accepting the confessions and such. I  downloaded it again and when I did it downloaded like a 'zip file' and it titled it self "ddlc-win" and when I opened it and opened the file "game" it did not have the normal application to click and it opens the game. I really needs someone's help.  Thank you in advance
