The Lobster Programming Language

Lobster is a game programming language. Unlike other game making systems that focus on an engine/editor that happens to be able to call out to a scripting language, Lobster is a general purpose stand-alone programming language that comes with a built-in library suitable for making games and other graphical things. You can also check out draft version of the full Lobster documentation, in particular the Language Reference.
