This is just my version of Lab #3 ("Invaders") in the book Head First C#, by O'Reilly Media. (Note: It's a really good book and anybody who really wants to learn C# should get it.)

Things I changed from the book's version:

• Every so often (meaning every time your score hits a threshold) you get an extra life.
• You can hold down S to get a random score increase.

Comments, feedback, and issues are much appreciated.

Go to bin/Debug and run Invaders.exe.
