This Widget is a reasonable facimile of Pacman. The Menus seem to be the only problem. When I launched this (10.4.1) I could only get the mouse arrow to turn into a selection 'finger' by clicking the controls item. If I clicked controls a few times I ended up on the controls page and couldn't get back from there.
The solution was to close the widget, launch it again double-click controls, then double-click start game. This took a few command+r reloads to work.
Once in game it works. The menu implementation is the only thing that seems problematic, but it is a critical problem and I hope it is remedied. Otherwise this is a nice attempt at a widget.
