Developing a webOS Game with Canvas
The tutorial walks through all the steps in planning and developing a webOS game from scratch. The author builds out a game called Far Out Fowl, which is something of a Atari era Kaboom! clone. The game includes accelerometer based controls, sound effects and exploding alien chickens. The author Frank Zammetti also include the full source code (on GitHub) and does a good deal of explaining the basics of developing a game using Canvas.
