Whoa, Castra! Nice combo there... I'm curious as to how well you'd do against a moving target ;)
For the rest of you:
I've attached two replays of my own, with some basic techniques.
You might want to run them through
this replay parser and figure out the details.
Mind the following when playing:
1. As opposed to regular toribash, it's best to hold all at the start of the match. There are so many forces at work on your tori that relaxing all throws you off balance.
2. To get into striking range, you will have to take a step forward. Contract both your ankles! It's too early to extend them, see 3.
Then move one hip forward, the other backward, and -extend your abs-.
That way, the weight is on the back foot, making sure the front foot actually goes forward. It's a confusing story, but try it out, you'll see what I mean.
3. Extend your ankle when your front foot hits/is about to hit the ground. If you do it too early, you'll fly upward, which makes you very vulnerable.
If done correctly, however, it adds a sudden forward impulse to your punch. When in doubt, keep your ankles contracted.
4. When toppling over, the C button is your friend! The forces that keep you upright will force your tori into a (sort of) balanced pose, even if you hold your joints.
5. Try holding and/or relaxing your arm joints when punching. They matter a lot accuracy-wise.
6. Practice some moves in single player before you try it online. It'll really help!
