It haves decent variety,but...
The gameplay becomes literally impossible later on,and this being a clone of NG-Duelled didn't help that much,too.
Platinum Medal------- I'm the Beast Duellist
Not a bad game, though it gets a bit tedious going for all the medals. For anyone else grinding through it here's a little tip I've noticed. If you begin a battle by clicking on your opponent's head (or nearest equivalent), most of the time this will damage them once for free. Nice little headstart.
