Explanations are clear and concise. Congrats. Really good job. I'd do several things differently, though in games this simple are not that vital. For example, in the Doodle Jump game, I'd reuse the platforms that disappear from the bottom to reposition them up again (with random X), so it wouldn't be necessary modifying the array, creating and destroying objects, shifting and pushing, and so on. Also I wouldn't use so many intervals but hey, as long as it works... :)

48:25 I think the glitching is happening if you press the same direction multiple times (ie you press left when the doodler is already going left) so it's creating multiple timers. I was able to fix it by adding -if (isGoingLeft) return- and -if (isGoingRight) return- to the top of the respective move functions, so if you're already going that way it'll just get out of the function. Great video!

The tutorial is great. But why I can't make these types of games on my own. It's really frustrating. And you just do it as natural as breathing. Seriously. I wonder what I do even lack. Do I have to follow these tutorials for the rest of my life.

great Video.
One thing i noticed. if you press the arrow key more than once you create mulitple Intervalls.
After the game is over we can only clear the latest one.
That is where the glich is comming from.
Keep up the great work -

What a bs. Is it really that hard to make proper platformer/flappy bird clone? Those projects shown in video are stuttering all the time and the only thing that you can do there is to pretend that this is real game

Thank you for the great tutorial! My fix for the glitches was simply to clear the left and right timerId intervals just before setting them again in the moveLeft/Right functions.
