Yes, the current tutorial is pretty crap. It tells you "here, press these buttons to do this cool decap move", but it would be much better to show the different joint states individually and show what they do.
It would also be great to show a quick presentation of the main mods - aikido, wushu, lenshu and tk, showing how the general gameplay works, and maybe a tip or two on how to play it.
Loading screen-style tips would work fine in the main menu, with some general advice, for example
*You can change the controls in the main menu (almost no one uses standar controls anyway)*
*Relaxing a limb when it's about to strike gives you more power*
*the forum has advice and tutorials on how to become better*
Do stuff like that, and we instantly have a more beginner-friendly game.
