Galixanar – underwater and movement
It's a simple shooter. Like retro games. Like Space Invaders or Galaga. You move left and right and shoot. Two lines of enemies. They're at the top. And a menu at the bottom. A fantastic underwater, space-themed look. And the signature 320x240 screen resolution. 64-color CGA palette. Everything is perfectly in keeping with the retro theme. And it's programmed in Free Basic using the GVim editor.
