Wait nevermind, it was because i use brave browser and guess what was blocking the game from loading, brave browser's security systems.
I'm just test it in Brave browser and effectively it doesn't work. I'll research about this. Meanwhile, you can play it in Firefox, Opera, Chrome, MS Edge, Internet Explorer or Safari.
UPDATE: if you use Brave browser you must disable Shield (click on Shield icon and switch off the interrupt)
Thanks!
