 ##### Space Invaders
 
+This is a very basic clone of the classic Space Invaders game. The implementation is short but leverages some
+of the more interesting language features such as async await.

 ### Basic Types
 
-For programs to be useful, we need to be able to work with some of the simplest units of data such as numbers, strings, structures, boolean values, and the like. Support for these basic types is much the same as you would expected for Java, with some additional features such as string templates, map, set, and list literals.

-In order to reference values they must be associated with a variable. Variables are declared with the keyword var or const. A variable can have an optional constraint by declaring a type. If constrained a variable can only reference values of the declared type.
