i dont know how to shoot truth bullets and i really need help i cant even get past the first debate cause i dont know how to shoot the truth bullets at arguments

you gotta click on the argument you wanna refuse! it's really tricky tho it took me several times to get it right since it's so sensitive

You need to left-click to shoot. As someone who has difficulty aiming, I suggest you make the debate play two times: the first time you aim, the second time you shoot, both aiding yourself with the concentration mode (SPACE).
