I've been really enjoying this game! Really satisfying chill puzzles. I love the trilobite trait "stubby lil' guy" because yes he is, so cute. The sounds are nice, I like the music and also some of the ambiant neighborhood sounds. There's something cozy about a nice window view and an old imac.
I have some feedback for some small things I think might be nice.
* Sometimes a fossil looks like it could go off of multiple branches and it just won't let you put it on the "incorrect" one. Sometimes it does let you attach in the "wrong" place. Being more consistent would be nice! I like being able to put it into the wrong place and need to adjust my solution, but if others would like it to only allow you to snap to "true" lines that'd be fine with me too. I'd like if there were multiple ways to solve some of them, according to your own preference for ordering.
* One of the first colorless fossils had by the "Colorful" trait, which is hard to tell when it is grayscale sometimes. I ended up having to randomly link it to a few similar fossils until it snapped to the right one, before I noticed it had extra shading. Maybe up the contrast when they're greyscale, or maybe it's just me?
