Ratatouille for the Nintendo DS transforms key events from the popular Disney/Pixar movie into a collection of adventure levels and touch-screen cooking tasks. In the adventure levels, you'll help Remy the rat to run, jump, climb, and sneak his way through intricate 3D environments in order to gather the ingredients necessary to prepare Linguini's recipes. Once you've collected the necessary ingredients for a recipe, you'll then use the stylus and touch screen to chop those ingredients, mix them together, and cook them up into the dishes that'll be served in the restaurant--just like Remy and Linguini did in the film. The game won't occupy more than an afternoon of your time, but you'll probably enjoy every minute of it if you're a fan of the film it's based on.
In the adventure levels, you climb up shelves and scurry around the pantry hunting for food.
All of the adventure missions take place in 3D replicas of the pantry, kitchen, cooler, and dining areas at Gusteau's Restaurant. The environments aren't huge, but they're intricately laid out. Each one has plenty of chairs and stacked boxes to climb on, sinks and stove surfaces to run across, and multiple layers of shelves that allow you to ascend from the floor to the ceiling. Your job is to gather the ingredients Linguini has requested without getting caught in too many mousetraps or being seen by one of Skinner's goons. Remy is an athletic rat. Using the directional pad and buttons, you can make him run, jump, climb up vertical wires, and perform a backward somersault that doubles his leap. You can also ride on top of melons to spring traps, and use springboards to hurtle Remy upwards. There aren't any enemies to speak of, at least not in the traditional sense. Instead, a meter gradually fills up to represent how close you are to being seen. The meter will decrease if you hide in dark cubbies or under overturned cans and boxes. If it fills up, Skinner will catch you and you'll have to start the level over.
After you collect the necessary ingredients for a recipe, you'll then have to make the dishes for that night's menu. This is accomplished through a series of minigame tasks that require heavy use of the system's touch screen and microphone. First, you have to cut and chop the vegetables and slice the breads and cheeses. As individual food items appear on the touch screen, you have to trace the stylus along the indicated lines in order to cut the food before time runs out. Next, you have to mix and cook the dishes. Using the stylus, you drag items from the side of the screen into the three different pots, and then stir the pots to make them cook faster. If a pot gets too hot, you can blow into the microphone to cool it down. Lastly, you have to plate and garnish the dishes. Much like the cutting minigame, this is accomplished by tapping and drawing the indicated patterns on the food with the stylus, which is supposed to represent laying down garnish and drizzling sauces.
