This style of tutorial seemed absolutely perfect to me! I learn best from a combined method and have attention issues, so I was able to be introduced to the information really well through your narration but will miss things or want more specific details so being able to pause and read was huge. Special credit for having well laid-out documentation that was more detailed than just a transcript of the things you've said. Having a few images of code examples was a huge bonus since one of the hardest things can be synthesizing these complex concepts into syntactically correct code as well as remembering whether it's used in a specific process. Sometimes those details are lost when deep in the middle of coding. Having heard a summary, read the specific documentation, and seen its place in the code all at the same time, it will be way less likely that I waste a couple hours looking for a bug when a function wasn't technically written wrong but just used in the wrong place (which isn't always intuitive and sometimes buried deep in the documentation). Of course the animations are also great. Combining all the variables and functions to understand their consequences usually requires me to open a test project and making stuff like that myself, so it saves me a ton of time. Also even though I've been doing this for a while there's still some concepts that I haven't had to deal with and the naming conventions can be a little ambiguous. A simple example is shapecasting as opposed to raycasting - even though its name is intuitive enough, seeing the animation of it makes it really concrete and I'm confident I'll be able to make quicker design decisions about when it's appropriate to use.
Sorry for the wall of text but I've watched a ton of different tutorials and devlogs, and I was seeing the critique you're getting, and I want you to know that your videos are the best I've ever seen (for me, not invalidating other people's preferences). They weren't just great for how the information is presented in helpful layers (voice, text, images, and animation) but your speaking style, audio quality, and graphic design was simply pleasant and really let me get immersed in the material. I really hope you make more like this because I know that my work will be seriously improved by them and honestly it makes learning or reviewing these topics actually a pleasant experience.
