City Tank - .6.2

Climb into your tank! The city of bricks has been taken over by an army of blue small, but dangerous, tanks. Save the city before it's too late.

This is my first real attempt at python and pygame. I've had fun making it, hopefully it's fun to play.

Arrow or WASD: move
Mouse 1: fires main turret
Space: fires tank machine gun
M: switches turret tracking modes

Use esc to go back to main screen incase of unexpected death.

Not many changes. Added a new tile, a 'steel' non-destructible. Made the map smaller, should run nicer of most machines. I'm trying to make it use less processing power. If anyone has ideas, they are very welcome. I'm working on making the AI more intelligent and less ignoramus.

Also added a simple profiler.
