Lisp Game Jam "Hard Mode" is a game jam taking place for a full 10 days, with a theme. It runs mid-October of every year. After the jam has finished, 4 days are given to everyone to try out the game submissions and vote for their favorites.

ATTENTION: This year's theme is: Darkness



Rules

Must significantly utilize the decided upon theme.

Must be written in any dialect of Lisp. This includes, but is not limited to Common Lisp, Scheme, Emacs Lisp, and Clojure.

You may use existing libraries, third-party or self-created, as long as they have an open-source license.

You may use existing assets, including but not limited to artwork, music, and sound effects, as long as they are free for others to use as well. You must disclose what you used, and give proper credit where it is due.

You may develop your own general-purpose engine, tools, and assets before the jam begins. This way, you can start with the gameplay during the jam. If you do choose this method, please make an effort to show that the gameplay was not worked on before the jam began, if you want to receive a good rating.

You may even use an existing game as a base on which to build upon. This method is encouraged for newcomers. If you do choose this method, please make an effort to substantially modify it enough if you want to receive a good rating. You must also specify what you changed, either from a commit history, or your submission's summary.

You must submit at least a source archive, either as a ZIP or tarball, with instructions on how to compile and run your game. To get the most people to test your game, you may also want to include pre-compiled binaries.

Within the source archive, please include an open-source license you are releasing the game under. This is important for people to use/modify your game for another project.

You do not have to target multiple architectures, though keep in mind that the more people that are able to test your game, the better rating you will get. Please make a note on which architectures are supported in your submission.
