Node Reviver: Open Source Ludum Dare Puzzle Prototype (GPLv3/CC-BY-SA 3.0)

Game development jams bring many lines of usually dirty code that power often innovative new implementations of various mechanics and rules. Ludum Dare requires source to be visible but neither code nor art has to be freely licensed.

I believe that the histories of TuxKart/SuperTuxKart, Warzone 2100 and OpenArena show that maintenance can be one of the strengths of the open source game development scene. Having more gamejam-made working prototypes available under "safe" free licenses would enable this community to pick up promising projects and slowly build upon them.

Anyways, one of the games that has more than proper licensing information and is both free, open source code and art is Node Reviver. A short description:

• Game mechanics and level designs intersecting with Pac-Man's PipeWalker's.
• Light neon colors on black background visuals.
• Bfxr sound effects (with sound sources included, nice!)

Ludum Dare, Game Jams and Licenses

Olofson's LD22 game

Free, open source licenses are underrepresented at game jams and contests.

This weekend's Ludum Dare ends in a few hours and it already counts 754 entries. The following authors mentioned open source licenses in the context of the compo/jam:

• roschdal plans on "releasing the game as open source on Github"
• Riley Adams's project is already there (GPL3)
• Agon's code is as well ("LICENSE: TODO")
• mcc released LD code as open source before, maybe it'll happen again?
• Olofson's (of Kobo Deluxe fame) failed submission is available (under LGPL)
• Furyhunter submitted a jME game (Not sure but seems to be GPL)
• kragniz's GPL game requires pyglet and pymunk
• lorancou made a HTML/Canvas game called lonekitty (GPL)

Here are some non-submission projects discovered on Ludum Dare:

• dwrensha released a SDL framework (GPL)
• KhaoTom mentioned the Spacescape skybox generator

A *lot* of other submissions use GitHub but have no license info. :(

I found above projects using this advanced Google search. Hopefully, there will be more results in a few hours, which would mean another blog post.

kragniz' in-progress

Here's a quick list of ideas how free licenses could get more attention in such events.

• Organizers could recommend free code and asset licenses
• Developers could offer porting non-cross-platform submissions in exchange for release under free licenses
• Participating developers, who already use free licenses, could advertise these in blog posts and announcements (more)

The Global Game Jam for example requires use of the CC-BY-NC-SA license, which unfortunately is non-free though.

Let us know of any freely licensed game jam/competition entries which we didn't cover!
