to always play the ball and not the man.

That expression, when not on the basketball court or soccer pitch, is easily misconstrued. :)

and remember that this series is for the begginers, so it is essential. and you think that was easy. these 6 videos took about 6 months of work. don't judge it quickly.

Time investment doesn't give you a buy on the quality (or lack thereof) of your result. You dropped 6 months on something and THEN asked for feedback, with your guard prepared for any negative criticism saying "but I spent so much time on it."

That doesn't work. I'm a horrible cook. If I spent all day in the kitchen making a full-course meal from scratch, and it still tasted awful, people aren't going to want to eat it. (Or if they do, it's painful and solely out of pity).

This doesn't sound like you're in search of feedback, but rather back-patting. People have been honest with you: the audience you're most likely to reach (active forum members on a game development site) are telling you that your videos aren't properly addressing the actual needs of beginners (people that want to start making their game idea). I think you're underestimating the knowledge already obtained by your average "beginner" game developer: anyone searching the internet for resources has found plenty of them.

The majority of your received responses here are of the "woah, slow down, change course before you spend any more time on the current heading" variety, and I'm willing to bet the downvotes are expressing the desire to keep quality information out there for people.
