1. Game info

controls (at game start menu only)

- F1 -				toggle between main menu and high scores list

WEAPONS
-------------
- High calibre AA HE shells. Heavy area damage, slow, low re-fire rate.
- AA MG bullets. High velocity, fast re-fire rate, but do little damage.

ENEMIES
-------------
- Fighter (250 points). Fast and nimble, but carries a few bombs at most.
- Light Bomber (150 points). Not as fast as a fighter, but carries more bombs.
- Heavy Bomber (50 points). Slow, but a few of those could level a base if left alone. Also drops paratroopers.
- Paratroopers (20 points). If more than 20 land safely, they will take over your base resulting in game over. "BASE CONTROL" status (top right corner) shows enemy ownership percentage.
- Bombs. You can shoot and destroy them before they hit the ground, or more importantly your AA positions.

v1.122
----------------

- game repacked, better exe compression (thanks to UPX), smaller install size.

v1.12
----------------
- couple of fixes and game optimization, stable as a rock now :)

v1.11
----------------
- fixed a sound bug that caused the game to crash

NEW in v1.1
----------------
- sound effects added
	- volume can be adjusted by using PAGE UP/ PAGE DOWN
	- volume settings are saved on exit for next game session
- some visual effects improvements
- gameplay tweaks and some bugs and inconsistensies fixed

GAMEPLAY CHANGES in v1.1
-------------
- AA guns/mg reload only when idle.
- AA weapons fire rate and reload time adjusted.
- infantry entering a base will no longer damage aiming. 
Instead, if more than 20 land safely, they will take over your base resulting in game over.

v1.03 - changes
-------------
- aa GUN shells make more damage and at a slightly wider radius.
- aa MG bullets hit planes only when close to targeted position (else they just pass through)
- slightly weakened aa MG bullets damage to planes.
- airplanes will spread their bombload more equaly now, so all bunkers have the same chance of being hit (earlier they would more likely drop bombs around center of the screen).
- added airplane animations for climbing/diving
- airplane speed is now affected by climb/dive rate


3. Thanks to:
UPX compression program (http://upx.sourceforge.net/) game exe file is much smaller now, resulting in overall shorter download time and with no performance hit.
