You know Donkey Kong the game right? Rescue the girl from the gorilla at the top of a series of construction sites, yeah? The thing is, though, Jumpman (later known as Mario) is extremely fragile. If he falls more than a few inches, it's instadeath for him, so you probably don't just jump off of girders willy-nilly.

Even though you totally can.

The edges of the screen are distinct boundaries. If you hit one while on the ground, nothing especially exciting happens, but if you hit one while jumping, you kind of bounce off of it and fly back the other direction. I pretty much only use this tip to grab the hammer on the left side of the final board.

It's not really that useful of a tip, I know, but it is showy. And you can't be Pro without being a little bit of a showoff, it's just too much fun.
