There are no "respective" palettes, though, the game cycles between day > afternoon > night > morning but you can play the stages in just about any order.
I believe he meant "respective" in regards to "each level using it's own set of time-of-day-palettes", unless I missed something and say, Marina Madness Midday uses the same palette as Techno Tower Midday?
Sure, I could have exported all four variations of every level, but I chose to export only the daytime ones, since the layouts don't change, and it would be a bit of a hassle to do all of them. Maybe I'll export them all when the object definitions are finished.
Hey, I just noticed that Botonic Base Zone acts 3-5 have the same area pasted at the bottom of each map. These areas aren't accessible in-game IIRC, right? They also appear to be using art that isn't used elsewhere that is also displaying with the wrong palette. Am I mistaken?
IIRC those areas can be entered through a doorway, and are basically bonus areas to get more rings. edit: You can see one at 1:20 http://www.youtube.com/watch?v=Nd32V1ywMA8
