You can end the demo by clicking the anchor on the island next to the elevator if you've done everything in available in the demo.
Two of the developers involved (Semih Parlayan and André Bengtsson) along with two other Uppsala University students have set up development studio TeamCrew (http://www.teamcrew.se/) together and already released their first full game, Frog Climbers, on Steam (http://store.steampowered.com//app/485120). Johan Öhman, while not official member of TeamCrew, Composed the climbing music. So half of the original Anchored dev team are still at least collaborating.
