There is no updater for this game. To move your old games over, control click on the application and open the Contents folder, also control click on the new version and open its Contents folder. Now drag your old Game Files folder to the new version. When it asks to replace it click Replace.

Seems like a nice program, but I'd like the ability to turn off the sound effects. I like to listen to music while playing this, and the effects become intrusive. I found a way to turn off the music but not the other effects. Alas, the develop's site does not provide any kind of contact information, so I'm hoping they read these reviews and implement this change.
