MilkSnake is an updated version of my old game Swear. It is currently available only on the Mac App Store.

Feel free to report bugs or request things in here, although I can't guarantee I'll add much functionality to the basic game. I might perhaps make a sequel at some point, if there seems to be any demand for one.
