VVVVVV is heading to a 3DS near you as promised: The game has been set for release on the Nintendo eShop next week. Starting December 29, you'll be able to grab the game (published by Nicalis, the company behind Cave Story and its various iterations) for a price of $7.99 on your 3DS, and take on the game's many frustrating yet ingenious challenges for yourself.
Or, if you've never played the title before, you could go try out the free Flash version, or play it on PC or Mac as you wish. It's a great and well-made experience for sure, but bring all of the patience you have. You'll need it.
