I think it would off been better if you could move in only eight directions like in super mario rpg instead of turning akwardly everywhere.

I have no idea what is causing the Level Editor to not open. It works perfectly fine in the editor though... Just download it, uncomment the addObject command in the level editor that adds the LevelSettingsEditor, and then it should work fine. In the meantime, I will work on figuring out what is causing the editor not to load properly.

There appears to be a gallery-exclusive glitch that causes the Level Editor to not open when you click it and press OK to the notice. I'll fix it later today.
