I was aware of sleeping and sitting but nodding is very smartly done.
I think swimming can be done too, with some extra edits on the arms for the damaged sprite on the right, but it needs some animation work too of course.
Probably unrelated, but I like the map in the preview as well, it's very nicely put together.
Another demo of the dynamic cloud cover system, this time complete with the original soundtrack composition (which sounds even goofier at this 2x playback speed). Much left to tweak but I like it so far.
