I'd like to buy it tomorrow but I need to know if it has subtitles.
Thanks.

Of course it has.

Is there a way to turn the subs off, and also not have to click after every line of dialogue to advance the convo?

when you start the game, go to 'Settings'

Then, click hover over the 2nd thing to right and it should say 'Game Settings'
Then on the top left, hit the Down arrow and then it should come up with some options and one of them is 'Subtitles'

Took me a while to find it lol

You'll get used to the clicking after a while, adding the spacebar to primary action (enter key can't be reassigned) really helps.
