I recently posted artwork from Taifun Rider's game Shuggerlain. An older version of this game is free to play, which you can find here: https://taifunriders.itch.io/shuggerlain. I wasn't sure how to source these posts, so I just included Taifun Rider's Patreon as the source. I think this had the implication that I was sharing paid art straight from their Patreon, which isn't true. This art can be seen for free in the free version of their game.
What's the consensus on a situation like this? Am I allowed to post art from the game if I use a better source?
