Sega have done a great job on the first Sonic game on the DS but it's not quite there.
STORY
Once again, Eggman has stolen the Chaos Emeralds and Sonic wants them back. Eggman has teamed up with (twin from another world) Eggman Nega. Eggman has also stolen the "Solar Emeralds" from a new female character called Blaze the Cat. Sonic and Blaze meet up and Sonic offers for them to team up and stop Eggman together. But Blaze refuses and tries to get the Solar Emeralds by herself (they have a big battle at the end). And so the adventure begins . . .
Story: 7/10
GAMEPLAY
You can either control Sonic or Blaze (surprisingly, Blaze has better powers than Sonic), each in their own little worlds. Tails manages to help Sonic in his adventure who sits at the top screen when you're choosing a level on the bottom screen. When you are Blaze, Cream (you know, the small rabbit) helps her. All the levels are 2D, which makes this a great Sonic game. The levels are fast paced (aren't all Sonic levels?) and take up both screens. If you don't know what I mean, say if you were controlling Sonic on the top screen and you jumped off a cliff. You would then fall to the touch screen. Only the boss levels are in 3D and the backgrounds look sensational. But sometimes in the game you can get very annoyed and you wish there were more checkpoints in the level. The controls are very simple. Use the arrows to move (obviously only the left and right since it's only 2D). A or B is jump which you normally use to kill enemies and bosses. Y or X is "power-up" which makes you speed up and R or L is block. See? It's simple, and that's what I like about this game, the controls are very simple.
Gameplay: 8/10
GRAPHICS
Sonic looks better 2D than he does 3D. You will never say "What? How did I die?" Unlike the 3D games, in this game you can clearly see what's going on. The cutscenes are cartooned (not that matters). Sega have done a great job with Sonic Rush's graphics.
Graphics: 8/10
SOUND
The background music has vocals singing some weird songs and raps like "Cha! Cha! Cha! Cha! Cha!" and "This is what you need!" and "Doooooo -do-do-da-doooooo!" You can tell there's been a lot of thought into the music of Sonic Rush.
Sound: 7/10
Overall, Sonic Rush is a good platformer for the DS and I recommend it for any gamers tired of 3D gameplay but it's not a number 1 game. You'll wish there were more lavels and it's over way too quick. I finished it in 5 days.
RATING: 7.5
