I want to contribute to this thread, but I don't even know if I beat the Temple of Seasons yet. I fought Winter (three times by accident), but the quest still says to Explore the Temple and there is still a stone wall up in the main room. Is the rest NYI, or am I somehow just missing something massive?
EDIT: With the last update, there was an end to the dungeon after the reworked Winter fight. For some reason, I was a version behind even though it said I had the latest.
Anyway, I thought the Temple of Seasons was fairly straightforward and very fun. I never really knew where I was going, but as I played I just wandered where I hadn't been, and it all worked out.
There are some vines I can climb up to a small, empty area, and a large vine leading down, but I guess they'll just have chests. I just don't wanna go back to get the future chests, but I'm just very lazy.
There is still the case of the right stone wall and the right wing's sun door, which must be larger rooms, but I guess those are secrets yet to come.
