PewPew 2 is the best multidirectional shoot them up on Android.
Expect retro graphics, megatons of enemies, and a frame rate achieved by no other game (except PewPew).
There are nine game modes, and a campaign with 3 levels of difficulties so even the weakes... *AHEM*
So even the strongest of you will have some challenge!
------------------------------------------------------------
And now, a list of the features:
-a deep story with drama, romance, and mystery.
-crops to grow and birds to throw, to keep in touch with nature.
-private information sharing with several companies, because we *care* about you.
-targeted advertising, so that you aren't disturbed by pointless ads.
Wait. That was a list of what's not included, here we go:
-frames per seconds (a LOT)
-9 games modes (2 of which must be unlocked)
-8 unlockable ships with offensive defense (bullets shot in every direction when hit).
-a campaign, with 3 level of difficulties and boss fights
-online scores, with replays
-awesome music
-XPERIA PLAY Optimized

A few notes:
-On older devices kill as many background app you can, this can considerably increase the smoothness.
-Seriously, kill them all.
-On some devices (such as the Nexus One) the touch screen has trouble handling touches on the same horizontal or vertical axis. That is why by default the joysticks are in diagonal. You can try moving the joysticks to the bottom using the settings menu, but it might result in poor controls.
