famous gaming youtuber Quill18 also has a side channel called quill18creates, in which he creates various types of games from scratch. His content is pretty cool! I listen to him at 1.5x speed. His channel is really good if you want to get into game development, especially with the Unity engine.
He's also got a Twitch stream (name: quill18). He mostly plays games but there's Patreon-funded content on the programming side now and then as well - the most memorable was probably him writing a simple tower defense game in an hour.
