Yea that gameplay video reminds me of why I wasn't so hot on gameplay. Even with a stylus, it was super easy to get snagged up with the controls with stuff get crazy. Having movement and attacks being tied to very similar gestures is probably the main con I had.
Probably why I kinda stop caring about being technical and just spam shit for most of the game.
Not trying to be condescending, but did you know that you could different sets of pins at the same time? Basically if you had different pins activated by the same command you could have one that wouldn't work unless you held down L or R. I used this a lot, 'specially in the end-game.
