Some moves contain a 'grab', and some styles have more of these moves. That challenge is working out when you are in danger of being hit by one of them. Also of course they will just use the normal grab.
This game has a very good potential.
The effects of it are great, and personally I really enjoy these kind of puzzle games.
Trust me, if I worked for Kongregate, I would approve this.
