Ninja Spinki Challenges!! is the new game from Flappy Bird’s famed creator, Dong Nguyen. The game puts players in the role of a ninja who must face a variety of mini-game-like challenges.

There are six types of challenges in total, ranging from avoiding a bouncing cat to throwing shuriken at creatures. Though six challenges don’t seem like many, beating one unlocks a more difficult version of that mini-game. In total there are five levels to each mini-game, so there are several opportunities to replay challenges.

The aspect of Ninja Spinki that aids replayability the most is Endless mode. Every time you beat each of the six main challenges, it unlocks the Endless mode for that mini-game. Endless mode is where the addictive, competitive element that made Flappy Bird famous comes in; it’s all about surviving as long as you can to obtain the highest score possible.

The game seems well-polished, and each of the mini-games is plenty of fun, particularly as you reach more challenging levels of each one.

Ninja Spinki Challenges!! is available on the App Store as a free download for iPhone and iPad.
