Yeah, I did eventually run into a few guesswork situations. But besides those, it was a lot of fun. On the 20% I really had to stop and think, because all the logic I already knew was there, but subtly different due to the number of neighbours, so new patterns emerged that I had to re-deduce. Still haven't successfully solved one! most of the guesswork I've had to do was around the edges. Maybe going somewhat down from 20% in total and having a smaller percentage around the edges could be a useful temporary heuristic until a potential solver is in place. I also spotted a bug I think, where when you fail and undo, some of the mines are rendered similar to an empty cell, thereby spoiling where they are. This was on Firefox.
