Thanks! Here's another update on my side:
I finished making the maps of the first (both inside and out) and second floor of our tower, which is the setting our protag is in.
The difference is minimal when you first look at them, but a lot of small things are changed between them like the patches on the wall, vines, leaves, and grass tufts. Also, even though the backgrounds look similar, the puzzles in these levels are going to be quite different as well.
Also it looks like we're just going to be using the same characters that I designed for the mockup in my first post, so I went ahead and animated the little ghost character in them. Will be uploading him later and working on the animations for the flowers and other animated background elements. Other things I've finished animating so far are the fountain and "your demise"sign. Both are very simple, but overall give life to the envirnment you're walking around in.
