Physical copy patch
We've just updated the Steam version of the game to 20180728-2986043. We're also releasing a patch for physical copies. You should have gotten a notification from BackerKit with new downloads. You can download the zip file and then overwrite the old files that were installed by the original physical installer. We will be making a patch installer in the near future that would automate patching CLANNAD.
You can view the patch notes here.
Lastly, we're running a Kickstarter for TOKYO CHRONOS, a New, VR Mystery Visual Novel Game! It only needs a few thousand dollars to be fully funded!
We're also supporting and publishing Wishes In Pen: Chrysanthemums in August - Otome Visual Novel it is 30% funded and with 23 days to go!
