I really enjoyed this event overall! Thank you so much!
Considering both the staggered quest releases in the summer event and the delayed shop release in this event, I feel there needs to be more clarity from the very beginning of any event on exactly how much currency we'll be able to earn and how much prizes will cost. Essentially, all mechanics should be presented up front. There's a lot to be said for players making discoveries organically in the main game, but not in a time-limited event.
I loved the idea of the creative prompts, but unfortunately I was unable to participate because, like others, I was already involved in NaNoWriMo, which is very time- and creativity-consuming. It would be great if this event could in the future perhaps be slightly shifted so it was half in a different month, or if at least the creativity portion were extended (for instance, announce the prompts a couple of weeks earlier) to allow us to budget our time and creativity a bit more effectively.
