Hello again, GuyWithTeaCup,
I posted a comment about a year ago, asking if I could use RoboOni as an example in a tutorial guide I was making for the Raycasting Game Maker. I'm happy to say the guide is finally finished and is now available on my Itch page. RoboOni made several key appearances in screenshots and video examples, so I wanted to be sure you knew about it.
Thank you again.
Here is a link to the finished guide: https://filmgamerj.itch.io/guide-to-raycasting-game-maker
