Interesting. I believe the developer of doodle jump is a solo developer in Florida. I was about to question the ethics of this coder cloning his app, but I noticed he kindly didn't release a working version.

We all learn through copying, but I have never seen someone who shared their copying process online... It's funny that it rubs me wrong only because I know doodle jump is a small outfit. If it was a giant faceless organization I probably wouldn't bat an eyelid.

Well, its not all about the "copying" process. Its the actual game making process used by the author that he shared which can be used to "copy" games. If that makes sense.

There is nothing wrong with cloning apps or games. It happens all the time and should be expected by all.

Remember copyright protects a particular version of an idea, as made to exist either on paper or as a computer program. It does not protect the idea itself (that is where patents come in).

The result is stated in the article, but deserves mentioning again; http://cssdeck.com/labs/html5-doodle-jump/8

I think this is pretty cool, but if you play it, you'll immediately realize that the physics are off (compare left/right motion with up/down/gravity) Is this just a basic problem with JS games, or a result of the compact implementation?

Yeah it's definitely off. x axis transitions are too fast.

Cool. I like the fact that his implementation in Javascript is only 630 lines of code. Seems like a good reference for game programming in Canvas!

agreeing with huskyr here. nicely done in so little lines.
