Kirby's Adventure is arguably one of the best games on the planet
The graphics are a 10/10 for NES standards. They're perfect. The sound is 10/10 aswell, it's perfect. All of the classic tunes that you hear today on Kirby's recent games come from this masterpiece.
This game has minigames for when you're not spending your hours on Kirby's epic adventure. It has a sound test and everything to keep you playing this game for hours on end.
All in all, this game for 500 Wii points is outrageous, they should be charging double that! I would buy it still. Pleas just buy this game, you will never regret it, especially if you haven't played this game before, trust me and GET THIS GAME!
