Don't ask people to make games for you. No one will want to make a game for someone who asks for someone else to go through with the entire game making process. In fact, not many people would even agree to make a game for someone else. You will have to learn C++ or something, and code it all yourself. That is your ONLY option if you want Ao Oni to be on the Nintendo DS. And no, don't try to say 'oh, but if this gets enough attention, someone will want to make it'. That is a lie. That will never happen. I've seen people claim such things before and it's never turned out in their favor.
In addition, you're in the wrong subforum. ROM Hacking and Translations is for hacking pre-existing ROMs or translating pre-existing ROMs into other languages. This would be an entirely new fan creation, so it should go into the Emulation and Homebrew subforum.
Is this game like Nanashi no game.
No, it isn't like Nanashi no Game. There are a few similarities, but nothing concrete enough to say they are alike. This game is more along the lines of, say, Sweet Home (NES) without battles, or Corpse Party (PSP).
