This is Alien Blaster game ported to Google Android.
I did not change anything in Alien Blaster sources, except for SCREEN_WIDTH,
SCREEN_HEIGHT and BIT_DEPTH constants in global.h.
This should be compiled with Android 1.6 SDK and NDK - google for them and install them as described in their docs.
You'll need to install Eclipse or Ant too

Then you can test it by launching Alien Blaster icon from Android applications menu.
It's designed for 640x480, but with bit of luck you can redefine your keys and play the game a bit.
It's designed for 640x480, but with bit of luck you can play the game a bit.
Note: You should play it with vertical screen orientation (keyboard is closed)
Fire key is Call key, redefine Choose Weapon to Enter key through (trackball click)
Other keys like Home, Back and End Call will force application quit, and because
the app itself does not handle SDL_QUIT event correctly (asks for confirmation),
it will stay in memory until you reboot device. The same will happen if the phone
goes to sleep, so hit keyboard often plz.
To exit correctly press Menu key - it's redirected to Escape.
