Hmm, something to adjust the animation speed would definitely have been useful. I made it rather fast due to being used to fast mode in various card games I play.
Another thing I might add is more intricate animations to make it easier to figure out what is going on. If I had enough time, the cocktail card was supposed to visually pour contents of the chalices, and the toast card would actually clink the two selected chalices...
Thank you for the feedback!
