A partial shot in the latest release 0.5.7. Better stars and explosions, 2 types of enemy ships, faster collision detection, 900x700 resolution, powerups and health.
Explosions! The frame title is OpenFlight 1.0 Beta, but this is really OpenFlight 0.5.6 alpha. All releases are alpha until 0.9.9.
These were the days I would use a minimal Linux windowing system. I didn't have a name for the game yet, so it was called Project X. I had to develop some pausing functionality to get this first screenshot.
