I want to help you learn how to make your game in GameMaker Studio.
The Coding Fundamentals Series is a great place to start if you're new to coding or just want to know how GameMaker does something. I also have a number of videos on various topics that can help you make your game—things like virtual keys, vectors, steering behaviors, GUI buttons, buttons in general, Git and Github, the broadcast message system, multitouch, and so on.
I keep my subscription list public and try to find and subscribe to channels that I think could be helpful for you. These are mostly other GameMaker channels, but I have some general coding channels that I think are accessible even if GameMaker is your first and only language as well as some game design channels that I enjoy.
If the videos are helpful, please consider supporting me on Patreon: https://www.patreon.com/samspadegamedev.
