There is a minor bug in ver. 1.02 and under that causes one more story ending than has been completed to be listed on the "endings" screen even after reaching only one ending. Encountering said error does not spoil the remaining story and will not significantly effect your experience in a negative way. However, if you wish to correct this on your copy, download the patch for ver. 1.03 here, which also revises some known typos:

Ver. 1.02 and under displayed the default Ren'Py icon when the game was not running. Due to a lack of thorough documentation on the matter, this was originally left as a known shippable. This has been amended in the newest version distribution. The patch also comes with instructions on how to update the desktop icon of a previously-downloaded copy for Mac users.

For newcomers, the downloads on the main page have been updated to the newest version on both Windows and Mac.
