Space Ranger

A retro-style vertical shooter, inspired by early-80s arcade games.

13 rounds, each with its own enemies, formations, bullets and music.
A boss guards the end of every round, and a giant flagship waits in
the final battle. Rescue the little people abducted by UFOs --
listen for their cries.
