I know this is just a demo project, but I thought the game was broken at first, since the portal gun didn't seem to do anything. It isn't until the third level that you can actually use the portal gun, and then you can only use it on the non-boundary lines (as in, you can't use the ceiling or the walls).
I appreciate the information the author shared in the blog post instead of just linking us to a game without any context.<p>For instance, he points out that the source demonstrates how to use Box2Djs for physics, handling touch/multi-touch/accelerometer, and auto-resizing the canvas.<p>It went from something I'd play around with for a couple minutes to a bookmark & a repo I'm now following. Thanks for the extra effort.
Very clever implementation. One thing I would comment though is, it's rather irritating to have the figure constantly moving left or right. It think it would be better if the figure stopped once hands were released from the keyboard.<p>Not sure if that's the intended functionality, but that's what happens in Chrome for Mac Version 20.0.1132.17 beta.
Very cool. But having issues in chrome/mac with the portal gun not shooting anything. Works fine in safari/mac.<p>Note: this applies even at and beyond the 3rd level where it is first useful.<p>Additional edit: I want to emphasise how very cool this. I wouldn't want anybody to think that my criticism is all I have to say about it. Great work!
