Yes, thanks, I think that is the game. And thank you for the link to the comments. I did a "Search" on this forum, but I did not find much discussion of the game itself. As far as I could tell, most of the posts were related to judging and ranking the HOGs of the year. According to the ranking, Botanica fell pretty far down the list.
I wanted to be sure I wasn't getting into something like Botanicula, which kept hanging me up with arcade-style pinch points and made me uninstall what I thought was going to be a really fun game. I love a fierce puzzle, but abhor arcade stuff.
