While designing a game, you would want to create the setting and the place where it all happens. Many games are divided into levels, often getting more difficult with each level upgradation. For some other games such as RPGs (Role Playing Games), there is no such thing as a level because it implies a certain cutoff with often no way back. Throughout the book, a space that can be saved as a single file in the Weltmeister will be referred to as a level.
The Weltmeister is literally the tool to master your world in ImpactJS. If you installed ImpactJS correctly you should be able to access the level editor shown in the next screenshot by placing the following address in your browser:
