2. Playing with example universes
After starting the program you find an empty universe. As a good starting point you can open an existing simulation from the examples.
For instance the delivered simulation file replication.sim shows replicator machines at work.
You can simply run the simulation by invoking the play button. alien delivers standard navigation functions such as zooming and scrolling.
Furthermore an edit mode can be activated at any time (also during running simulation). That mode is only recommended when using a high zoom level.
