We may run the "Create a new game" function by clicking the toolbar button "New game":
In the first screen, you have to input a name for the game and select the project's directory.
Click "Finish" button when you finish all, and then OGM will create
the new game project and open it (with its first scene) in the IDE.
Once a game is created, you may edit its details by double clicking its name in the resource list.
