Are you, like me, terrible at reading go kifus?
Do you, like me, have paper records of suspicious origin but don't have a way to easily digitize them?
Then this tool is for you! Simply click on a spot, input a number, and repeat a few hundred times to scan in your record of the game. Afterwards, the left/right arrow keys allow you to go through the game, highlighting each numbered move.
If you're a dan-level player, you might actually get more value out of the game by not doing this process, but I don't know. I'm not a dan level player, and looking through paper records is a lot of work I don't want to do.
Warning, this program is super hacky and basically requires a real board in front of you as well. It was made in a day and so does not have actual game logic.
