Well blackthornprod is about the most intuitive stuff I've seen in terms of tutorials, though if you're not familiar with code may have to pause for a bit.
Regards player controller here's an example of making one in unity, though you can also get premade ones that you simply attach to a character or object
That is the first of a 4 part series where that exact game shown is made, each episode about 10 min.
If you want to try very small simple games simply following along with some of these tutorials, will allow you to basically have an entire game after 30min-1hr minus the final polish(you don't need to know all the code nuance simply type it down, and put your assets, though many of these youtubers tell you what the code is doing as they go along). Of course most people would be missing the art. These simple games help you get familiar with the stuff for when you are going to handle more complex stuff.
While a coding language may seem intimidating the alternatives are not significantly easier, and if you later need to make more complex behavior it will help to have become familiar with such on simpler code as used in small apps.
There was a recent challenge of make a game in ten minutes from brackeys, and many youtubers created various games in ten minutes. Whilst of course that is testament of what experience and practice allows, some of them actually showed practically the entire process of creation, which could help someone less experienced make similar games with minor modifications following within said time frames. Though I'd suggest getting familiar with the environment prior to watching such, with a bit of experience these can be easily followed though with no experience it'd be a bit more of a challenge.
If you want deeper understanding of this type of code Sebastian Lague youtuber gets deeper into it, he's very good at explaining stuff(which goes from beginner to quite complex). Though you can get away without needing to know the nitty gritty.
Another technique that some developers seem to use is the combination of multiple premade assets(controls, music, graphics, etc) to produce games with minimal effort. I recommend unity because of the large asset store, if you want to do something, there may be assets that already do the thing and are plug and play
PS
I personally recommend unity, not only does it have an ample store, but it has very large number of youtubers as well as udemy courses covering different aspects of it. If you go to one guy and don't like his style of teaching there's another guy with a different style which may be more to your liking. Big community is always important, that large number of people teaching the basics as well as more advanced concepts combined with the more vibrant discussions online make it easier to clear doubts and grasp the engine.
