Interesting news: Neo XYX sounds like it is a remake loosely based on an indie game called XYX. You can even see if you watch some of the videos, that the graphics from the one screenshot, and the first level graphics, appear to be based somewhat on graphics from this game.
In regard to XYX, from another forum
So....is this a port onto the Neo?
NG Dev Team:
Not really, it's just based on this game. Gameplay, graphics and music are new and specifically made for the Neo version.
Here is lots of info and videos of XYX in action, from the creator. http://gzrgames.blogspot.se/search/label/XYX
It is a PC game that sounds like it was made with one of the variations of gamemaker (though it looks pretty good, retro in a good way, imo). And here is a link to a 3 level demo of it!http://sandbox.yoyogames.com/games/1131 ... mo-version
I haven't tried out the demo yet, but if this were just a "mere" port of the same game to neogeo/DC, I would probably still be happy and buy it. It looks pretty awesome from the videos.
