i know about old trick "jump before crouch / climb up / etc", but how to use it to make entire run be a little bit faster with each good jump?

You have to hit space within one frame. There's really no tips to it. You just get a feel for it. But it's not that worthwhile of a timesave unless you're one of the top players.

Yeah, I probably forgot something, but that's what I know about them.

As a newbie (who sucks at bunny hops) I found looking at the space bar lighting up on the nohboard helped me with timing. I'm still not insanely good, but it's helping me find the rhythm.

okay hear me out

allow bhops on scroll then make a no bhop category to compensate.

ur welcome ;)

Why do you even follow this game still Andy

I expect a return soon

I already kinda good at timing, but i dont know where i should bhop, anywhere where i can, or on perfect flat plases / something like that?

Watch a few speedruns of your cateogry and copy where they bhop.
