... Yes it is easy, same way you get in houses, rocks, trees, or even in the air ^___^ position your screen sideways, then hold down A or D / Basically hold down left or right so you are running sideways, then it bugs in certain areas and glitches you up down wherever..
In caves/mines you can get through walls and hide this way ^^ and await your prey and pwn em when they are not expecting it LMAO... Many applications to this
My favorite is going under water in different areas or even in the middle of tullan
Sometimes this can be done by clicking excesively until you bug to a spot, but the easiest way is holding down left or right run (A/D).
Hope that helps
have fun with it
*There are very tall mountains North of Asylum towards terranoa
There are also bugs on the ship in the sky that can let you run across the air everywhere, or put you underneath the game terrain
(Underneath the inside texture looks like cheese hehe
