The new 2D Doujin Fighting game by NRF, the guys behind Big Bang Beat!
Full original characters (not based in any game/anime/hentai game/etc) with characters desing by Shouji Sogabe (Senko no Ronde aka WarTech in the US).
Trailer here, seems that works on a GGX-like resolution on the sprites, and awesome thing for a Doujin game.
Another 2D fighting game for a too awesome year.
