Last week we posted about the Indie iPhone Holiday Sale, a joint effort from six developers, each with fantastic indie titles, to raise money for Penny Arcade's Child's Play charity. It really doesn't get more win/win than this. For $6, you get six great games, and some of the proceeds go to helping improve the quality of life of kids in hospitals across America.

The following games are still on sale until the 2nd of January:

To celebrate raising so much cash for kids in need, Semi Secret Software made a substantial announcement: Canabalt is now totally open source via the MIT license. This is the full latest version of the game that hasn't even been approved yet on the App Store which features some pretty sick OpenGL optimizations I've been told, allowing the game to run at 60fps on recent devices.

If you're a pioneering iOS developer, check out the source here. The license they're using is open enough that you can basically use the game engine for anything you want, provided you're not redistributing the game code, graphics, or sound. This really makes me wonder if we'll see a Canabalt spinoff that features all the unanswered suggestions from our forums.

Either way, this is great news for the developers participating in the sale, developers who are interested in looking under the hood of Canabalt, and most importantly: The kids benefitting from these donations.

    Not meaning to plug our game or anything but Supastar runs at 60fps on any device, including the 3G, and it has more advanced graphics than Canabalt. Obviously on more recent devices you get the high-def and what not and a few extras.

    The idea is making your game Open Source is certainly an interesting one.

    • E_Domina

      It depends what you mean by "advanced". I checked out your game and I think the retro feel in Canabalt is more pleasing to me.

      • eBattalion

        Not trying to knock Canabalt, it's a great game! Simply pointing out that 60fps is not unheard of for this type of game.

    kids charities are ubiquitous. How about having a charity for the forgotten and discarded of our society, the elderly!?

    • Andy

      Good god I hate the morons who complain about whatever charity is being supported. How about never speaking again?

      • Zephram

        Looks like I struck a cord with little Andy, what's the matter, your mamma didn't give you any Christmas presents this year?

      • Zephram

        I can't stay mad, therefore I forgive you Andy for calling me a moron. Happy New Year!

    Canabalt can really use a update-I mean the last update was in 09 lol

    • ImNoSuperMan

      I dont even need to check the update history to tell you it's been updated after 2010. Its a universal app and unless Semisecret know the semi secret about ipad in '09, it definitely got an update in 2010 😛

    The MIT license doesn't assert any restrictions on redistribution.

  • Dropper

    I checked out the code - what a mess, and nothing special there. 🙁

    • urhash

      Ok, genius, mind telling us your game in the App store?

  • Carl

    Just FYI: its definitely December 31 and Spider: The Secret of Bryce Manor is back up to $2.99 (at least in the Canadian store)
