I actually had fun.
But I don't know if it was a design choice—probably... having to press 3, then 2, then 1, even though I might have been faster if I could have hit 2 first (since it reaches the center faster than 3)—but that's just a thought...
The fact that the numbers swapped around was fine, too.
But what I personally didn't like at all was that the keys suddenly changed... that sort of thing isn't for me.
Still, I had fun overall. ^^
