The patch to upgrade the game from version 1.0.0 to 1.0.2 can be downloaded from this post.

If the patch is installed, there should now be a sub-folder called "BackupFor1.0.2" inside of the BoneCraft installation directory.

Though I agree with maybe making the version of the game that is running more visible to the user. Maybe have it display at the bottom of the screen at the game's main menu (where you can start a new game, load, change options, etc.)?
