well i just finished this and i was surprised at just how different it was from the ps vita original. media.molecule continues to prove they are without equal as far as sony's first-party studios are concerned. i really love that they managed to make the dualshock 4 seem like an interesting piece of technology, although it's not as impactful as when they did that with the ps vita.
it hurts the message at the end of the game too, where you actually have the game's world in your hands and your own stupid face is the sun. never liked that they called it a 'you' though. both games are strange in that they're well-designed, but have dumb stuff like that just casually tossed in there. they also make a good case for never ever having voice acting in a video game for any reason whatsoever. ugh.
glad i played it though. i needed something a little shorter after paper mario (and between ace attorney cases).
