In Hello Kitty: Day at the Park, players take on the role of Hello Kitty, My Melody, Kuromi and other characters to playfully compete for the most epic day of fun at the local park. They explore the park by laying tiles, ideally gaining items along the way that allow them to complete adventures, which they will document by taking selfies. The game's dynamic mechanics ensure each playthrough is a unique experience. The game features a unique system to scale all parts of the game in difficulty for each individual player, even while the game is in progress, so kids can start with the simplest version to begin to explore the game's mechanisms, then learn the more advanced gameplay when they feel ready.
