Hey man thanks, I have no idea about a release time. I have to build all the levels and improve artwork. Still a lot to do. Id like to have it finished and published by the end of the year but not certain.
EDIT
Here's a basic example to point you in the right direction: basicElevator_artpunk.c3p
In a nutshell the elevators use bullet and solid behaviours and a container to group a jumpthru object that gets pinned to the ceiling and another object pinned under the floor that kills player if he gets caught underneath.
Containers are great because you only need to position the elevator object in the level and the other container objects are automatically created. You just need events to position and pin them.
The movement is controlled by instance variables. On start of layout, instance.var 'positionY' is set to be self.Y. Instance.var 'distance' is manually set in the layout. So if you want the elevator to travel 4 tiles on y axis enter 64 (4x16px tiles).
