Along with the fun 2-D stages and some impressive boss encounters (right on par with the ones from the first game), Sonic Team also included some fun water vehicle stages. Over the course of each stage, Sonic collects components, which Tails can then turn into a watercraft that progresses in development each time. Sonic starts out with a jet ski, pushing enemies out of the way, collecting rings and performing tricks in mid-air with the help of touch-screen strokes. He eventually works his way up to bigger vehicles, such as the hovercraft or a submarine.

The graphics explode with color, with lush, tropical backgrounds whizzing by in the distance and levels demanding exploration. The animation looks top-notch, with the integration of 3-D graphics into the 2-D setting working very smoothly. The music is decent considering the theme of the game. Jungle beats and other techno-like tunes play in the background. The sound effects are mostly drowned out by the music, although ring-collecting effects come through just fine.

Adventure's multiplayer mode also deserves a mention. With the help of Game Sharing and Wi-Fi Connection options, players race against each other through a number of stages, collecting as many rings as they can while heading towards the finish line.

Had Sonic Rush Adventure come with a more refreshing game soundtrack and more memorable characters, it would've been a perfect DS game. Regardless, the fact that Sonic's back in fine form, especially after a couple of less-than-favorable console entries, is worth celebrating. Adventure manages to keep the hedgehog's head above water, reminding us that the K.I.S.S. method -- keep it simple, stupid -- still works after all these years.
