This version adds a level monster editor. It also fixes bugs and improves the user interface.
Files created with version 1 will work normally with version 1.2. However, if a file saved in version 1.2 that includes starting position resources is edited and saved in version 1, starting directions in those resources may be lost.
The readme file has been updated to document new features. It also documents where in the Insmouse No Yakata ROM the data patched by InsmEdit is located.
The Example.imp file has also been updated to illustrate the new features.
