Jett Rocket II was a lot worse than the first one, I agree with you there, but I found Nano Assault Neo an improvement over the 3DS original, it just felt more balanced and polished.

Its short and a bit unbalanced if anything were to be my complaints which makes the gameplay, particularly from the latter, swing wildly from play session to play session. I've had entire starting levels go by without a power-up and struggle to finish with decent points, to starting levels where I end up with 4 Sats and a V-gun and fall asleep at the helm.
