One of the founders of id Software, Tom Hall, has just started a Kickstarter campaign for a platform game creation tool called "Worlds of Wonder". Tom Hall who helped develop such gems as Commander Keen, Wolfenstein 3D, Doom, Deus Ex as well as a couple of Duke Nukem games (the good ones) and Terminal Velocity.
The tool will also include a "spiritual successor" to Commander Keen entitled "Secret Spaceship Club" , which is a terrible name for a game but it also demonstrates what this tool can do.
The Kickstarter campaign is off to a slow start trying to reach it's 400,000 goal but it does have 25 days left. Intended platforms for this are iOS and Android tablets, Ubuntu Linux, Mac, and Windows and users can share their levels across those platforms.
