I'm on mobile, I clicked through and I had no idea of what I'm supposed to do. Perhaps there's a tutorial that's expected to be shown and wasn't, if not, I'd suggest you add one, the linkedin games ones have usually good ones to use as inspiration.

Otherwise, an "hint" button is always a good idea to help with frustration.

Edit: once I finally understood the rules, it's a pretty nice game!

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.
