This is the first time I've even seen this game. It's not horrible, but the graphics is not super impressive, and the enemies are a bit predictable and uninspired. There is a new block move, similar to Capcom's Knights of the Round: you press back and attack simultaneously, and then hold back until an enemy attacks you. Quickly after impact of an enemy attack, they will often be open for a counterattack. The big armoured knights are very vulnerable to this technique.
I reached STAGE 7, 'THE GATE OF FATE', which is a great name. I was killed by a birdman.
