This may be the first must buy 3D Classics game!

The original Kirby's Adventure was a simple and fun title, expanding the first game, Kirby's Dream Land, into a franchise and unleashing unto the world one of the most unique and adorable video game heroes in existence.
It was much, much longer than its predecessor, featuring hidden switches to unlock new areas of the world maps, branching paths throughout some stages, trickier bosses than ever before and, most importantly, the introduction of Kirby's copy ability, allowing him to steal enemies' powers and weapons and use them for himself. The game received almost unanimous praise in its increased length and difficulty over the original, as well as the whimsical design and execution.
Despite all the love though, it was bogged down by a few small problems of glitchy backgrounds and screen borders, and frequent slow-down during action-packed levels. You usually couldn't use Kirby's Crash attack without a small amount of lag before the animation and sound kicked in.
Fortunately, these shortcomings are completely eradicated in Arika's 3D revamp of the NES title. One of the first things to note about the game is how incredibly clean it looks, with nary a glitch to be seen. In fact, on the smaller screen of the 3DS the old 8-bit graphics compress tightly together into a rich, colorful world full of charm.
The 3D does wonders for the presentation of the game. Platforms and walls crop out in front of the backdrop, while doorways recede away into the back, inviting you to see what lies beyond. Backgrounds have multiple layers of depth as well, making for some gorgeous cloud effects. For a 2D platformer eternally locked into a side perspective, the amount of contrast is very impressive. Suffice to say, 3D really does improve on the original game, making you look at the levels in ways you never have before.
Being an enhanced port rather than a remake, there's not much to mention besides the graphical changes. It's the same game as always, with no new content to discover besides a recorded high score in the game's boot menu.
If you already own the NES version on Wii's Virtual Console, the visual additions may not justify the comparably large price, but Kirby fans are urged to check this out. If you loved the original game, get ready to love it all over again. All of the performance problems of the original game are gone and the surprisingly captivating 3D makeover stomps any other signs of aging firmly into the dirt. It was fun then, it's still fun now, and if this is a taste of what's to come in future 3D Classics titles then I'm greatly looking forward to them.
