From what I've seen of this,it's more or less the same as the first,saying that,it doesn't seem bad,theres nothing wrong with just improving the formula to make something that much smoother and fun.
The default mono modes are a lot harder. The input response is instantaneous, so if you go back to playing the first, it's like you're playing with Dead Space level lag. So if you're up for a challenge, I'd pick it up.
