dance dance revolution

I had a playdate today at Ridges house ( ridge is a church friend).We played some sort of vidio game called dance dance revolution.You dont have any control or anything. You just follow what the person dose.So you have this sheet thats where you step on. And you pick a charecter to do a dance.The only thing you have to do is follow what the person dose. But trust me its harder then you think.Sound pretty cool right? well bye!
