Firefox 4 Demos: Runfield – a Canvas Game

Yeah! Another awesome demo in Web’o Wonder!

With Hardware Acceleration and a fast JavaScript engine, the web platform is ready for Games. Runfield is an example. This HTML5 Game has been developed by Ilmari Heikkinen. It’s based on Canvas 2D, and this game works on all the recent browsers.

(small definition version here – Oh! and check-out the little built-in level editor)

    The logo doesn’t really fit, but the theme artwork is really making a lot of the game engine. Very smooth!

    Nice demo.
    It mostly runs fine in FF 4.
    However, it looks, feels, and sounds noticably better in IE 9 for some reason.

    Should at least comment that they’re “inspired by” canabalt.

    Why has my post still not been approved?
    If you are not interested in positive feedback that could potentially improve FF, then I will not waste anymore of my time here.

    This is very impressive, and runs nice and quickly on my machine with hardware acceleration enabled. But there is something about the graphics and the speed they move past that makes it really uncomfortable to play. Perhaps it’s just me, but I’ve played other games with very fast moving graphics like Sonic the Hedgehog and I haven’t had this problem, so I don’t know…

    I just played this game. Awesome :) . It’s interesting, more than Angrybirds.

    @Jethro Larson : Canabalt is better but it’s a real game, this is just a demo.

    But i am surprised to notice that this demo uses ~58% of my ressources where Canabalt use only 12%.
