can someone help me with abh over the thing

here's the save (i've got ride of the save due to restarting the run).

It's called ABH over goo. You need to get 3 ABH Then uncrouch (like if you wanted to do a standed ABH); then it might works. It's a really hard technique and you should try to learn easier strats, man.

wait how mutch speed do you need to hit the platform?

A lot of speed. It's a trick that even the top players have trouble with.
