An adventure based on NES classic Balloon Fight. Alice's little brother Jim has accidentally taken flight thanks to holding too many balloons. Alice must grab her own balloons and give chase.
Alice has two balloons to fly around with, and she can drop and reinflate them as needed in order to navigate the scrolling stages. If an enemy hits your balloons then one will burst and you will be harder to control in the air. If both burst then Alice drops down, and if she isn't above safe ground then she will lose a life.
You can also take part in a Balloon Trip mode or a 2-Player race against Alice's rival Sam.
Ported and published by Character Soft in Japan, Hello Kitty World is a Famicom port of Balloon Kid starring the Hello Kitty character. Aside from the main characters and colorization, the gameplay, graphics and music are the same as in the Game Boy version.
Balloon Kid wasn't released in Japan on the original Game Boy, but nearly 10 years later it was released on the Game Boy Color, exclusively through the Nintendo Power download service. As well as a color overhaul, the game has a new title screen, menu and map.
