In 2005 Hal Laboratory Kirby: Canvas Curse, a Kirby spin-off for the Nintendo DS where you have to draw rainbow lines with the stylus (or using your finger, if you are feeling daring) in order to guide Kirby through a stage full of obstacles. Ten years later, in 2015, that game finally had a sequel named Kirby and the Rainbow Curse, for the Nintendo Wii U.

While the gameplay is pretty similar, there are many differences between the two games, with the main one being the art style: While in Canvas Curse you are in a world of paint, in Rainbow Curse the main setting is a world of clay, which looks stunning, and is easily the most beautiful Kirby game ever created. The attention to detail is huge, and you can see lots of imperfections and dents in the models, which make them look like real clay figures.

Aside from that, the gameplay also has some differences. Unlike Canvas Curse, where Kirby could copy abilities, in Rainbow Curse the only times he gets different abilities are some levels where he transforms into a vehicle, similar to Epic Yarn. He can be a rocket, a tank and a submarine, all of them with their own fun gimmicks and gameplay, so they are a nice change of pace that don't feel rushed or forced, which shows how much effort went into the game.

Finally, the optional content is totally different: In Canvas Curse there were extra stages and medals that you could get by completing the main levels with limited ink/time, while in Rainbow Curse you have an entire section of quick challenges that you have to beat under 15 seconds. You need to beat four (sometimes twelve) of these challenges in a row to get a golden medal, something that can be frustrating at first, but after a while you get used to the fast speed and they become really fun and a nice change of pace when you get tired of the normal levels, which are a lot longer and slower in nature (which isn't a bad thing at all, of course!)

You can also get chests in the normal levels that unlock three things: Diary pages (one per level), character figures with pretty funny descriptions and music remixes of older Kirby entries. They are some of the best optional unlockables in the franchise, as they are really creative and fun to experience, especially if you are a Kirby fan who can appreciate the fanservice.

In conclusion, this is a really fun and charming videogame that has a lot to offer aside from the amazing art style, and I enjoyed it a lot more than its predecessor. Easily one of my favorite Kirby entries, and it's a shame that you can only play it on the forgotten Wii U.
