Good morning.

Not so long ago I recorded a test video:

There is no voice on the video, only some kind of subtitles.
I would like to know whether to continue, an overall assessment, and of course, tips on how to do better.

I'm going to rewrite the video with voice, paying more attention not to the actual implementation, but to why the implementation is done this way and not otherwise.

Full version of the drawing game
Developed version of the toy for educational videos

Typing code is hard enough for long videos, and this is a long video. Look at egghead.io/lessons/angularjs-animating-the-angular-way , it makes no sense to type from scratch, you can type some minimum and show how it works and show what will happen if you change something here, but here what - something to add.
You lose a lot of space on the right, you could open a browser there and build a video in such a way that you could see what was happening there.
Pauses must be cut, in my experience the video is shortened by 30%.
The sound is normal, just either get a pop filter, or make it yourself.
And so the ideal for me has always been railscasts.com , great presentation, good sound, and ~10 minutes long.

The drawing tool is very simple, although this is a plus for a trainee, but on Habré there was already somewhere about a drawing tool on Canvas in a more advanced version.
The game loads my weak computer a little less than 100%, apparently problems with rendering. In general, I can guess offhand, but it didn’t work out from one foray due to time constraints that everything on the screen is redrawn every frame, and this is known to be a deadly sin in the world of JS / canvas and I advise you to fight it first of all.
And it’s somehow strange to look at the page text without html/body/head tags, etc. Of course, I understand that everything works without them, but you position the code for people who want to learn something from it, and this is a bit obligatory)
