Independence Day for Mac

Your ship constantly runs from lef to right, slowly descending. Below are some buildings. The player must press space to drop bombs and destroy the buildings before they are so low that they just crash into them.Gameplay for the main part is complete. There was to be a boss section which would involve a genuine bitmap background and Lemmings/Worms style destruction and I seem to have fully or near-fully coded that but never incorporated it.Originally the game was a 320x200 DOS friendly thing that used Allegro + a separate sound library. I`ve converted it to an Allegro/Dumb mix, fixed up some scancode stuff and added high score table saving. I`ve also incorporated a software scale to 640x480 for the OS X build in order to allow full screen play - although it causes that version to be incredibly slow when combined with the paunchy Allegro library.
