The game can be used to make level maps using "Construct Mode". All of the enemies, options and the terrains and their music that are available in the main game are available. These files are saved as "CONSTRUCT.TXT", and can be emailed to friends. They can also be shared online, which is normal in many Eggerland communities. Eggerland for Windows 95 and Revival! Eggerland haVE more available terrains and music files, but all releases can load the same files. However, "Eggerland 0" does not show their new terrain objects.
