Found this great website to compare different HTML5 engines! Do check it out: http://city41.github.com/breakouts/

Hope it helps you choose an engine

Wow, that is cool! That is pretty selfless of the author to make 5 different versions of the exact same game. Must have been quite boring

copy and paste for the most part with a little bit of change of entitiy framework but thanks to him for doing it.

BUT this shows nothing really. The code behind this does not show heavy use of any engine as far as resources. running code, graphics, ect.. Hard to gauge from this hence why they all run basically the same. A good gauge from this would be him showing the time it took him to build from scratch each one.

The logic would be the same, but the implementation of the various HTML5 engines is quite different. I have used Crafty, Impact and Lime, and a lot of the source would have to be re-written. Since the game is not extremely complex, it was likely a week or two project, but t is still nice to put out the effort to put it all online.

Yeah, the engines can't be compared based on the game playing. Instead, I think the real value is in downloading the code and comparing that. It could be an easy way to see which engine's structure is the best fit for your coding style. Or a way to compare relative complexity (I still feel that Impact is the most simple HTML5 game engine, even after using others, but that is my opinion).

I agree it helps seeing the style ofcoding in the different engines and seeing which one is more to your style. There is also a table on there with comparison of the different features of the engines, I feel that also helps decide which engine meets your needs
