Great game, really fun!
A bit glitchy though. Sometimes I stop in mid-air (when there are no obstacles in the way), while other times I can pass that part without any problems.
It's also a bit slow (low FPS), even though my hardware can take pretty much any game without any problems.
Also, just wondering, shouldn't this game be called 'Furtive Jian'? Because a dao is a Chinese broadsword, and the hero in this game has a straightsword (jian).. ;)
