The source code for Episode 6: Menus (releasing on YT today) has just been uploaded.

This episode gave me some regrets about the structure of menus (an array where a struct would have been much better!).

I am considering creating an "optimized" version of the project after the tutorial series has finished, where I can make some extra little changes for people who just want to use this as a solid "engine" rather than follow the tutorial series. We'll see how it goes.
