No offense, but just no. If you don't like the art, but the artist that's fine, absolutely no problem here, but supporting a person like J. K. Rowling financially by consuming their creation is actually a problem and should be opposed.
This view is enabling horrible people and not okay.
I am playing Railbound after it got on sale this week. Some of the extra levels are really hard and I have yet to find a solution.
Overall it is a fun little game which works great on the Steam Deck.
