The second update brings an in game editor so you can create your own puzzles and share them with other players. You can read more about the editor here. Changelog:
- Create your own rooms using in game editor
- Share rooms with the community
- Fast forward mode
- Bug fixes
You can get the update by patching from within the game or you can re-download the new setup and install over your current installation (saved games will be preserved). Desura users will get the update automatically of course.
Above is the new official trailer showing off some of the editor features.
