Hmm…I pretty much know these tricks already, didn’t know the first one, but that was flawed anyway. Though i already knew about the second thing. Well, I got to it. I think Lori is pretty cool, just having the lack of a high jump can mean that she can’t pass some custom made SP levels. And some high places, in MP, will require running and jumping from somewhere, which takes more time. Copter ears aren’t generally considered as useful in MP by some people.
But, I know some more tricks!
Wallhax. Or wallkick, doesn’t really have an actual name, tiles 16 pixels wide or thinner can be kicked through with Lori, though you need to kick at a certain place. You can also kick through 1 tile warps with it too.
Also, if a thin wall has an item beside it 1 tile above, you can stand at the corner, or kick at it, and you will get the item.
If the floor isn’t too long, and a spring is blocking you in the way, you can kick through it. I actually found this out in lazily made JB levels.
EDIT: Just fixed a mistake.
