No that truly is all there is to this update...It seems that the guy who did the art for his CG's got commisioned to do CG's for a new Visual/graphic novel by some big circle,so they were forced to come to an end with this game's development as neither of them have the time for it anymore(well from what i can gather there's two of them...one does the game programming spriting/scripting/whatever,and the other guy basically draws and designs stuff,and both of them like castlevania series)...
Anyway he plans to release a full final version of the game sometimes later(like a 5-6 months from now),which will feature enchanced CG's(in a quality sense),and maybe even a CG gallery...
Well this game's development was fun to observe until the end,and it's a pitty that we won't see more,but all good things eventually come to an end...
