Luftrausers is perfect on the Vita in the same way Vlambeer's Super Crate Box was perfect on the Vita. It's "perfect for the Vita" because it's a great game. While either title, with their minimal arcade sensibilities "make sense" on a portable (with buttons) for their quickness, you're not likely to play Luftrausers for just ten minutes on your commute.
You're more likely to miss your stop because you mashed "up" to launch, craving one more run. This time you'll do better. This time you'll kill that blimp.
