First of all. The famous Prt scr trick
Here is the way how to do it
First. Click E and W Also spam Prt Scr if your trying to get up ficho tunnels' walls This is also helpful if you are stuck in a mesh.
This is not that much used but here is the way how to get up high places!
This is similar to the E W PRT SCR trick but this is easier
First you should hold jump and once your character lands and starts a new jump quickly press prt scr and you go higher than normal.
Note: You cant do the jump high trick on air it will send you to the ground quickly instead.
If this is hard to understand here is some gifs of it.
