"Kirby and the Rainbow Curse is a video game in the Kirby series currently in development by HAL Laboratory for Wii U. The game is a follow up to the 2005 Nintendo DS title, Kirby: Canvas Curse.
Kirby and the Rainbow Curse carries on the style of gameplay from Canvas Curse, presenting the game with a unique modelling clay look. Players use the Wii U GamePad to help Kirby, who is stuck in a ball form, move across the level by drawing rainbow colored lines on the touchscreen to guide him. Making Kirby go through loops will speed him up, whilst touching him will put him into a spinning attack to use against enemies. Kirby can gain various forms throughout the game, such as a submarine, a rocket, and a tank."
