"Would you say its okay if i just stick with the "youtube run" forever?"

Well, it is a game, just take pleasure with it

When I started running, I was just happy to make 2-3 steps then trying to not fall... Who care if you are doing youtube or custom run ?

I don't.

If you do, continue playing, don't make pressure on yourself, things will come by themselves with habits.
Habits in Toribash are like setups moves that you can recognize and you will "know where you are going" when you are launching a move.

Habits come with experience. Experience come with time.

It is pretty cool that you can do some running steps in a few hours ;)
