This month's project is a 3D invaders / surviving game. It all starts easy, with only a few enemies...
However, things get complicated quickly, as you move on to harder levels.
The player has a protective shield that gets activated automatically, but this drains energy.
Shoot the blue powerup that appears at the end of each level to recharge your batteries. Take care, the powerup appears in a random position and will only be visible for 3 seconds!
A good player will reach the end of the game (after the 4th level) if he or she is constantly moving, not allowing the enemies to lock-on their target.
The code is very well commented, as always.
