Champion Island is a summer sports-adventure game that is a series of interactive doodles that celebrate the Tokyo 2020 Olympics. The game was developed by Google in collaboration with Studio 4°C, a Tokyo-based animation studio. The game lets you play as Lucky, a calico cat athlete who explores a world filled with seven sport mini-games, legendary opponents, and dozens of side quests. You can join one of the four color teams and contribute to the real-time global leaderboard. The game also features a rich and colorful pixel art style, inspired by Japanese folklore and culture.
