Twinvaders multitouch shooter

Fend off the hordes of insectoids, space lobsters, and other intergalactic arthropods attacking from two sides with your twin guns, shooting in two directions at once. A hectic retro shooter inspired by Jeff Minter games like Laserzone and Hellgate. This game is 100% free with no ads. It was released as an entry to the 1GAM contest. I will likely release it as open source soon.

Controls:
Swipe on left side to rotate left gun, swipe on right side to rotate right gun.
TIP: use your thumbs.
NOTE: a multitouch device is required.

This game demonstrates the multitouch API of the JGame engine. It has procedurally generated sprites, backgrounds, and sounds.
