I should add a tutorial with images because a lot of people were commenting thats it's not very clear how the game should be played, thanks for not giving up trying to understand it!

I tried everything and I still don't understand. Left/right/middle click everywhere, typing numbers on the keyboard, space, enter... What is happening?

you start with all the cells being inside the loop you need to click with a mouse left button or touch on the edge tiles of the loop to exclude them, if thats not working then it could be another problem.
