At first, we wanted to make a 360 degree first person panorama as in Myst IV: Revelation. The ambiance of the game is amazing, but we considered the time needed on code development and gave up working on panorama for now.
We developed some demos on Wintermute but are not sure yet whether to continue using this game engine or not for the game. Although there are still a lot of things to do, early trials showed that we may push the limits of the Wintermute. You will love this game!
