It sometimes happen to me that when I delete a command in VIzzy (by drag and dropping on the top right corner), the command will be inserted on a "below the delete button" command field.
Thus I suggest adding a "dead zone" around the top right delete zone.
If I'm not clear please comment so I can explain maybe better :)
Thanks for the game
I've ruined so many programs because of this. Especially on mobile, with my fat fingers.
