Can’t speak to the hardware question but the game itself is definitely worth playing, especially with headphones.
It’s one of the few games that I think everyone should experience at least a little of. The puzzles can be a little meh, and the combat is fiiiiiiine, but where the game really shines is in its atmosphere, world design and use of FMV and audio to really sell it’s story and put you inside the protagonist head.
Tearaway was designed from the ground up to be played on the Vita and I’d say it does a pretty fantastic job of using that hardware well. It’s also super cute.
