this is a great joy to hear! While I know people play my games, rarely do I get a word back, so this is just wonderful :)
To answer your questions, you always tell each other your turns, but they don’t have to give away everything about your creatures, just hint at parts to them. Additionally, if you do give something big away, consider if your civilization would be able to figure this out, or if they would act without knowing this history. Finally, as there are 52 weeks in a year (cards in a deck), and 4 suits (seasons), you do move through each shuffled suit fully before going to the next season (aka rotation).
and worst case, my games are built to be flexible. So, house rules are always encouraged!
Keep on miscommunicating, and thanks for playing!
