The 3D environments in the adventure levels are rather impressive. If you land on a bag of flour, a white puff will erupt. If you run through a flaming cooktop, Remy's fur will turn dark and smoke for a little while. As it is, Remy has a healthy range of animations. Watching him ride a melon like a unicycle is hilarious, and seeing him use his back legs to push his way onto a ledge is just plain cute. The 2D and 3D food items and pots in the cooking stages aren't nearly as impressive, but you'll be too preoccupied by sliding the stylus around to care. In both types of levels, your actions are accompanied by upbeat Parisian-style music and whimsical sound effects that mimic the film's atmosphere. Meanwhile, the story is told through scenes displayed between stages that consist of still images taken from the movie along with some text dialogue. Overall, the presentation is about what you'd expect from a polished DS game, though it would've been nice if they had recorded some speech clips.
Once you've gathered the ingredients, it's time to chop, cook, and plate the dishes in the cooking game.
Each adventure mission takes about five minutes to finish, while the cooking tasks usually last five or 10 minutes. You're always on the move in the adventure levels, and Remy's smell ability ensures that you'll never get lost. The cooking minigames aren't terribly difficult, but using the stylus to chop veggies and stir boiling pots is actually quite a lot of fun in small doses. All told, the two alternating styles of play complement each other. The downside is that the short levels combine to make a relatively brief game. You'll blow through the whole story in three hours. There aren't any side quests or hidden bonuses to lure you into replaying missions. However, you can kill some extra time by playing the stand-alone cooking minigame. You can even beam a copy of it onto a friend's system and compete to see who can finish the dishes the quickest.
Short and sweet is the story with the Nintendo DS rendition of Ratatouille. The adventure levels are lively and the touch-screen cooking game is very engaging, not to mention in line with what Remy did in the film. It's just a shame that the game can be polished off in a single afternoon.
