Yoo Ninja! Free

Yoo Ninja is a platform game set in a gravity-flipping world.

Your aim is to lead the little ninja through the platforms and avoid falling into oblivion. To do this, you have to tap on the screen. This will make the Ninja jump from the ground and gravitate over to the next platform (even moving upside down).

It’s a simple concept and we have to say, a simple game. Perhaps too simple. There are no enemies on the way, just two ninja stars chasing you that will kill you if you don't run fast enough over the platforms. This makes it a bit boring and it doesn’t seem to get any more difficult as it goes on.

There are two different modes: Story, where you will have to pass certain stages until you complete the 34 available levels in 4 different worlds; and Endless mode, a never-ending level where what matters is how long you stay alive (the longer the better the score you'll get).

This is the free version of this game, with ads. If you want you can upgrade to the paid version (HK$14), but make sure that the paid version is available in your country.

Yoo Ninja has been developed by RunnerGames.Studio, a promising Android game developer who has launched several titles on the market.

Yoo Ninja is entertaining. It's simple, it has cool graphics and runs smoothly. It's just too simple though, and we think there’s some definite room for improvement. Give it a try if you’re looking for a good time-killer, but as far as we're concerned, you’ll find much better options on the market.
