Workflow
Dummy subworld added by default: 24x24, with starting point at the left and goal at the right, both at the bottom.

Click an element on the tabs to select it. For some elements, click on the + button on the bottom right of each element to open the properties panel. The mouse cursor will show the element that will be added.
Click anywhere on the main window to add the selected element to the level. Click on an empty space and drag to add multiple elements.
Some elements have variations: use the mouse wheel to change the variation of the active element.

Properties
Properties are the characteristic of every element that can be changed, like the walking speed of an enemy. When the player selects an element on the right tabs, the properties panel will show the data of that element. Changes made in the properties panel will affect all instances created after that.
However, if the player clicks on the + symbol on an element which has already been added to the level he will be able to change the properties of that instance only.

The different values that can be applied to each property are locked: this means that for example the player will be able to select slow, normal or fast walking speeds for an enemy, but won´t be able to set the speed to an arbitraty number.

Structure
Each level will consist of the following data:
Name
ID
Timestamp of creation
Timestamp of last modification
