Mars Invasion Beta2

Firing is with "a" & "space". You can not be harmed until all bunkers are destroyed.

The Game contains 5 Level so far, but is still in Beta and will be expanded continously.
This is my first try to code a game, I´m regulary a CG-Artist ;)
Tips & Feedback are welcome.

Have fun ;)

// Update 13.04.2014:

Gameplay:

- number of Levels increased to 10
- Level difficulty has been changed
- firing rate of player increases at Lvl 5 and 10
- Bunkersystem changed at Levelup -> now the rest of "Bunker Life" from old Lvl is given as a Bonus to the new Bunkers

Decoration:

- decreased background action a little bit, but in fact it should irritate the player a little bit. War is hell ;)
