We actually promised (on Twitter actually) that we will be announcing the release date last week... but we didn't. Well the thing is we couldn't, but for a good reason. We managed to get Steam's agreement the last minute, and wanted to finalize the details before the announcement.
So yes, the game finally have a tentative release date, which is on 12th June 2011. As of now, we are implementing the Steam SDK, things like achievement and hopfully more.
Tobe's Hookshot Escape, the flash and Windows Phone 7 version will also be released soon(within the month), once we've got a sponsor for the flash version.
