Survival Kids: Lost in Blue is a survival adventure game released by KONAMI on August 25, 2005, for the Nintendo DS. It follows a teen boy who washes up on a deserted island after a shipwreck and teams up with a stranded girl to survive and find a way off. Players use natural resources like water, food, and wood to meet basic needs. The game makes full use of the NDS touchscreen and microphone—for example, collecting items and crafting tools via the touchscreen, and blowing into the mic to start fires. It features a "dual scenario system" that lets players switch between characters to experience different storylines and survival challenges. Multiple endings, determined by player actions and character relationships, boost replay value.
