Play as either as Sonic the Hedgehog or Blaze the Cat, in this throwback to Sonic's 2D days
Overview

Sonic goes down a water slide
Developed by Dimps and overlooked by Sonic Team, Sonic Rush is a very classic Sonic game in appearance. Similar to the early Sonic the Hedgehog games and the Sonic Advance games, Sonic Rush plays along a 2Dimensional plain. Each screen of the DS is used entirely for game play, as the player will stay centered in the center of one of the screens. After ascending of descending far enough, however, the player will switch from one screen to the next.
Sonic Rush allows players to play as both Sonic the Hedgehog and a new character, Blaze the Cat.
Plot

Blaze going up a loop!
Blaze, a cat-like creature from another dimension, has mysteriously landed in Sonic's Dimension. Sonic and Blaze's dimensions each seem to share certain similarities with each other, such as Doctor Eggman and Eggman Nega being after each dimensions emeralds, the Chaos and Sol Emeralds. Blaze discovers that Doctor Eggman has the Sol Emeralds in his possession and works on getting them back. Blaze runs in to Cream the Rabbit and, despite normally being a reserved individual, she befriends Cream as she travels through the unfamiliar territory.
Meanwhile, Sonic is on a similar quest to get the Chaos Emeralds, and is facing a familiar but different foe, Eggman Nega. Similar in appearance to Doctor Eggman, Eggman Nega is the alternative to him from Blaze's dimension. After Tails discovers that the dimensions are beginning to merge, Sonic starts to pursue Blaze, who he became suspicious of when they met earlier in the game.
Players are able to follow the story of either character, with the other protagonist and their companions showing up at points in the game. The levels played by each character are the same, but they appear in a different order.
Gameplay
The moves available to the player are similar to the earlier Sonic games, with the exception of being able to dash in mid-air and perform tricks while in the air or on rails. Levels are centered around running quickly through them, rather than exact platforming, which is a good fit for the series and plays to it's strength. The player must avoid traps throughout the level, whilst navigating through the levels and their multiple paths.

Each of the characters performs similar moves. These often differ in appearance only, as their moves have the exact same effect. For example, pressing down on the control pad whilst running with Sonic will cause him to roll, whilst Blaze will spin round and round on a point.
Tension Gauge
The Tension Gauge is used for super boost within the game and is situated at the left hand side of the screen. To be able to super boost, the Tension Gauge needs to be charged and this can be done in many ways. Whenever you perform trick actions or defeat an enemy the Tension Gauge will charge a little bit. The Tension Gauge will change color from blue, to orange and then red, indicating the amount of energy you have earned. When the red gauge is completely filled and the star icon on top of the gauge is spinning, the boost action can be used freely. However the Tension Gauge will decrease with time or if you have been hit by an enemy and take damage.
Levels
The game has a total of seven levels, two acts and a boss fight at the end of each level.
- Leaf Storm
- Water Palace
- Mirage Road
- Night Carnival
- Huge Crisis
- Altitude Limit
- Dead Line
