Damn. You beat me to it.
why map it to the flat button? that button is usually a map button on lots of games. I hate games that have bad control layouts. don't they play test things? I'm sure the vita version had something to do with how the buttons were mapped but c'mon guys, the first time playing with it killed it for me. half the time it doesn't even work, I mean I'm not sliding my finger perfectly enough.I wouldn't g as far as calling it frustrating. Inefficient is the word I'd use.
