I got an email from Lewis Mitchell, creator of Platform, last week. Somehow I assumed that it was a new project, and that there was only one level at hand. Seems it's been official for the last 17 weeks. That means, since it's an episodic web game, that there are 17 levels available for you at the moment. I haven't had the time to play all of them, but they seem to draw some inspiration from SNES classic The Lost Vikings and other puzzle platformers. It's got traps. I love traps. I suggest you give it a try.
Here's a link to the Platform archives.
