Upgrade 1.20

[Hakko]

Perhaps I'm missing something, but I couldn't find any instructions for actually patching the game. I bought the full version after playing the demo, but the download of the Mac update has no executable or instruction file. It looks like I could replace the files in the game package by hand, but I'm reluctant to do so if there's an easier or more fool proof way.

Any help would be greatly appreciated.

Thanks.
