I do understand that. It doesn't appear you mentioned this though (It's entirely possible you did, I did skim through after all ๐ )
I think an important thing to think about, at least in my opinion, is it would be better to teach scalable practice from the getgo, as a lot of beginners are looking to make these in the context of a project they're working on.
For instance, it could use the opportunity to teach how an instance editable variable works, something that is extremely useful in unreal for setting up level objects. Just something you might want to think about for a future entry, as teaching blueprint communication seems quite important, as it confuses a lot of people, so relying on a single get actor of class, without highlighting it's downsides and it's preferable alternatives may be detrimental in a tutorial ๐
I like the showcase of a lerp, and how it works, as well as the not often seen side of using widgets on top of the gameplay, but I see so many people struggle with proper blueprint communication, so thought this would be worth a mention, as I'd love to see more resources being published that cover it's often hidden positives and negatives.
