A great game.
The game has alot of levels and mini-games aswell as quite a few characters. You can also unlock special content that allow you to do extra things aswell as re-fight some of the games awsome bosses. The bosses are actually some of the funnest boss fights i've played in videogame history, amongst the well designed levels.
Nintendo pulls off another great game with Donkey Kong 64. Truly an amazing game.
