Somebody stole my work and made a game using my scenes. (Patreon)

A supporter showed me this Steam game page, just from the preview I can see at least 3 of my scenes have been used without getting my consent first.

Although I'm flattered, this is not cool :) I've contacted a high school friend of mine who is an IP law attorney in California. We will be pressing charges next week(gathered a lot of evidence over the weekend). I haven't been involved in any IP lawsuit in the US yet, this is my first one. Let's see how it goes :) I'm kind of excited to learn more about US's justice system!
