If you thought that NinJump Rooftops could have done with more competition then NinJump Dash might appeal to you.

It is, essentially, NinJump Rooftops with a focus on multiplayer races against real people - your Facebook friends and randoms.

Each race is comprised of four competitors, or I should say, four ninjas. The action is in real-time, so the outcome of each race will depend on your focus and reactions.

Aside from jumping over obstacles, you can pick up power-ups to chuck throwing stars, shoot rockets, and zap portals to overtake your opponents.

Taunting is a vital part of showing off and causing the competition to make mistakes out of anger, too.

To distinguish yourself online, you can outfit your ninja in a variety of costumes, including a pirate's garb, a chicken suit, and robot gear.
