The end of the Festival of Giving is supposed to be on January 8th. All the files are built and ready to be uploaded to the Steam server. However... I am stranded in Iceland until the evening of the 9th without my laptop. Winter storms forced Delta to cancel my flight. Therefore, my honeymoon is extended for 4 days (yey!), but I must postpone the festival rewards (sad). If all goes well, expect the update with the rewards Tuesday evening.
As an apology, I will let you in on a secret. If you payed for the max donation (200,000g), there is a choice that gives you one of two rewards. Try both decisions by quitting and loading your save game to see each reward.
Thank you for your understanding! I will post some honeymoon pics of me and my wife here for fun! :-)
