did you happen to buy the file? if so, thank you, you really didn't have to (read game description). either way, when you download the game theres only two files, index.html and script.js, and to open the game you just have to double click the html file and open it in a browser (microsoft edge works best). if you want to edit the files, then just add the folder to whatever text editor/IDE you use and naturally you'll be able to edit anything.
