Cave Story hitting DSiWare in North America over a year ago, but Europe is still waiting for an official release. It looks like the region will go without the delightful title a little longer, as it has failed certification with Nintendo of Europe. Responding to a question on Twitter, developer Nicalis noted that Cave Story was submitted to NOE in December but failed because of "some really minor crap with the manual." Nicalis hopes to submit the game yet again sometime this month.
Keep the faith, European Cave Story fans! Or you could always pick up the 3DS version.
