Hi Mr. Yabsley,
I commented on Templar about a year ago, asking if I could use your game as an example in a tutorial guide I was creating for the Raycasting Game Maker. The tutorial never became a video series like I intended, but it is now a fully fledged PDF guide book which I just posted to my Itch page. Templar was one of my favorite games made with RGM and I ended up using it for several examples of different aspects of the software.
Thank you again for allowing the contribution.
Here is a link to the completed guide: https://filmgamerj.itch.io/guide-to-raycasting-game-maker
