do i press - c + space + c ?

an explanation or clip will help, because I'm not understanding how you boost with the items, i am also using the older version.

Im pretty sure you just nod your head up and down whilst you throw it.

im not that good at the old version but the way you go like straight up is by pressing spamming space + e a couple times and if you wanna boost on top of the table thing its space + c

also there is a tutorial in the guides section
