Story of idea
This idea comes 1 day before I came to HackWestern. When I was seeking teammates, I found it is difficult to find one who knows the same technology with me, so I chose to think an idea by myself. So finally, after a day-long brainstorming, I got this idea.
It made for everyone who has a mobile phone. This game is very easy, the only way to control is to hold screen and move your phone. Easy to learn. Easy to play.
