Meh it's not really confusing at all. Well perhaps it could have been when no-one explained it properly
Hey does anyone know how many lights Tomoya got all together? I know there was that one from his father(That was the obvious one) but one came out of Fuko's sister in the 1st season(Just rewatched and saw that) and one came out of Komura-sensei. This was clannad episode 5... Did these lights actually reach Tomoya? (There may have been more but I didn't notice them)
I don't think he collects them. He probably just sees them and go "wah! I light... " =P
I don't think there is... However Clannad(The anime) tells a small portion of the overall Clannad story... I suggest trying to find the visual novel which is packed to the gills with Kyou awesomeness..... Of course if you follow the anime path you'll find Nagisa waiting at every corner....
And all files work as at last month when I downloaded them so don't worry.... The voice patch also works but not in the way you think it would.... There is no voice for the character you play(Initially called Tomoya but you can change the name) but there is for everyone else(Including Kyou)
