The touch object provides multi touch support, as well as detection of double taps, touch speed, accelerometer access, etc. I'm not sure why you would be getting a delay with the touch object -- it might be helpful to mention if you actually tested on a phone, or just a desktop browser -- but you should stick with that if you're building a game around touch.
Hey mate, thanks for the explaination!
Yeah... I've tested on my iPad but seems very unresponsive with the TOUCH object... I'm trying to make a flappy bird just for testing and if I tap the bird double time it just do the first jump... If I want a double jump I need to tap wait one second and tap again...
