When you have a map with multiple levels, each level provides an interlevel teleport to the next (or some other) level.
How do people typically END a project? If you have 10 levels in your project, how do you end the 10th level? You can't really teleport to anything that makes sense.
In other words, how do you indicate the person has 'successfully' completed the project? That is, how do you set up a 'Game Over' indicator (to be overly simplistic).

Thanks! Interested in your ideas!
