I'm glad you like it! I actually made my first prototype right before last Christmas so I could play it when my family got together, and people enjoyed it so much I just kept working on it.

As far as gifting goes, I actually didn't know you could get Steam gifts that deliver later, so I'm not entirely sure of the answer, but I assume if they charge you for the game right away it would process the payment then too.

Full disclosure though, only one person needs a copy of the game to run it and play with a group. Everyone joins the game by visiting a website (generally on their phone), similar to how Jackbox games work. So there's no obligation to gift copies, but if you still do I will be quite honored and grateful!
