So, per the tutorial, go into the game folder, right click > Open in Terminal
Type in this command:
.\ClickHer.exe --remote-debugging-port=1111 --remote-allow-origins=*
Now open a browser window, go to localhost:1111
You should see a link, click that, and a preview of the game should open. Start playing.
In the browser window, click on the Console button, type "allow pasting", press enter, and paste in the codes in the examples.
Worked for me.
If you follow the instructions in the YT tutorial exactly, it doesn't work and the Terminal and browser will tell you the connection was refused, and you need to add the remote-alow-origins to let the browser access the program.
Like-wise, trying to paste anything into the console will prompt you to type "allow pasting" to, well, allow pasting (you can also just type in the commands manually, but pasting is easier)
