Utsurun Desu.: Kawauso Hawaii e Iku!!! is a platform game for the Nintendo Entertainment System featuring Kawauso-kun. Notable for its innovative approach, the game includes deceptive title screens and allows the character to navigate the background to avoid obstacles. Additionally, attacks require players to press and hold the attack button, cycling through special moves with limited time to activate more powerful options.
While ostensibly a traditional platform game in which the player controls Kawauso-kun, the game has gained renown for being one of the earliest titles to attempt to break away from the video game conventions of the time. Among other convention-flouting novelties that the game offers are a series of fake title screens that the player must pass through at the start, and the allowance of the main character to traverse the background at times to bypass pits of spikes that otherwise appear impossible to cross.
In addition, the character's attack requires the player to hold down the attack button as the game cycles through the possible special moves with the more powerful attacks only highlighted for a short period of time.
