Guardian is a little game I wrote in Delphi. It is as sort of remake of the classic Defender. You need to fly around and protect the miners on the surface against the alien kidnappers. The miners turn the crystals on the surface in power ups. These power-ups help you defend them. When all the crystals are mined the level is finished.
This project is not realy finished. I might get back to it once. There is currently only one level, but see if you can finish it with all your miners still on the surface (it's not that hard). My high-score is 4333.
I used DelphiX for the graphics but somehow it will not compile properly in full-screen mode. So the game runs in a windowed screen. It runs best when your screen is set in 32 colours.
