Those of you probably has already known Umineko no Naku no Koro ni by the sound novel or the anime. This particular game is a fighting game featuring the characters of Umineko no Naku no Koro ni although it’s not the complete roster.
This game is similar to Melty Blood or any other 2D fighting game with the exception that you can pick two characters (it’s kind of like a tag fighting game) but the health bar is shared between your characters. The health bar also has 3 levels so you can be sure to do lots of combo to finish off your opponent faster.
There is a story line on the arcade version but too bad there is no English patch whatsoever for this game. The graphic is quite good for a 2D fighting game. Its quality is close to that of Melty Blood and I love the intro before the fighting starts.
I think the rest will be explainable if you watch the video.
