This project is now officially closed to Hacktoberfest 2023, will probably be open to Hacktoberfest 2024.
NOTE: The default branch was originally named master. It's now main. If you forked prior to that change, please take the appropriate option to realign the branch names.
Pull requests should generally correspond to open issues. You may file issues, but I'm free to close them as "won't fix" or otherwise reject at my discretion. Pull requests should always be for the main branch. I'll decide when to update the gh-pages branch.
As this is supposed to be quick and dirty, I'm not interested in moving to ES6 or any later versions of JavaScript. And definitely no Node and no NPM. I don't want an overly complicated dependency tree with who knows how many traps for the unwary.
CSS should be limited to standard features available in the major Web browsers
(Chrome, Edge, Firefox, Opera, Safari) without special prefixes (-moz, -ms,
-o, -webkit).
HTML5 for the most part but XHTML 1.0 and 1.1 are acceptable.
Maybe vector graphics are okay, but definitely don't use any raster graphics.
If you wish to add a level, it must be a level with at least one valid solution.
Except for an extremely easy level with a very obvious solution, the existence
of a solution must be proven either by stating the solution (use the
div.solution style) or by posting the level on game-sokoban.com and showing
that at least one visitor to that website has been able to solve it.
Also, the level must have only one player token (pusher) and the number of boxes must match the number of goals. However, template levels must have two player tokens and more goals than boxes. Though I'm not too keen to add template levels.
Be sure to indicate your authorship of the level both in metadata and the actual body text.
