Just took a quick glance at this. Not a bad tutorial at all but my only complaint is the technique section. Half of the techniques such as double leg are near to impossible to do in a normal game.

Plus, these techniques aren't really techniques. I can have a leg grab which turns into a lift/shovel then turn my body and do a suplex.

My suggestion is to rename this sections: Types of attacks instead of techniques and to get rid of some of the useless ones. A technique to me is more like a style such as grappling, striking, or a player who holds/relaxes at end of turn, etc.

And also to add more stuff relevant to an actual match such as a simple counter to a simple shovel (comes with experience obviously)

Some of the ideas such as relativity and weak planes are to far for people to understand such as myself so maybe fix that up.
