Go board game for Love2D
The dragger gui object 
works by clicking and dragging up and down to change its associated value.
The game requires GNU Go so that it can be used as an "Oracle" to generate board positions.
Getting GNU Go for Linux and Mac users is a fairly straight-forward process.
For Debian/Ubuntu users:
apt install gnugo
For Mac users:
brew install gnu-go
For Windows users, binaries can be downloaded at http://gnugo.baduk.org/. It doesn't come with an installer, so the binaries need to be manually extracted to the folder C:\Program Files\gnugo\.
