I really liked this one! Sonic Rush is a mostly solid time from start to finish. The levels are fun to run through do to having pretty solid level design overall, including having one of the series best water levels, Water Palace. Not only that, but this game introduced the boost system, letting you plow through the levels at high speed once you build up the boost gage through defeating enemies and using tricks. This game also introduced Blaze to the series, and as a far Sonic characters go she's one of my favorites. Her arc in this game is pretty simple, but done pretty well, and the fire techniques she uses give her a distinct identity when compared to Sonic, even if they're pretty similar gameplsy wise. The soundtrack in this game is also incredible, even by the Sonic series' high standards, with a lot of memorable and catchy tracks, like Back to Back, Ska Cha Cha, and Wrapped in Black. Another thing Sonic Rush nails is it's special stages. The half pipe from Sonic 2 is reused here, but this time with incredibly tight and responsive controls, some if the best from the system in my opinion. This makes Rush's special stages one of my favorites in the series. I do have two complaints with Rush though, the first of which are the forced enemy encounters used in some of the levels, Mirage Road in particular. These moments slow down the pacing of what is other wise a pretty fast game. My other complaint with thus game is it's bosses. While I think most of the bosses are fine enough, such as the final boss of Sonic and Blaze's campaigns, they all have way too much and it just causes them to drag. I want to bring special attention to the game's first boss, which has a one-hit KO move for some reason, something that no other boss in this game has save for the previously mentioned boss of F Zone. In spite of it's flaws, Rush is still a personal favorite of mine, and something I can see myself replaying as much as Sonic 2, 3, and the Advance games.
