Basic Button Controls:

First thing I'm going to do is lay out the control scheme for you. It's pretty basic and minimalistic:
cn_A = Jump
cn_X = Collapse yourself
cn_LT = Left arm raise
cn_RT = Right arm raise
cn_LS = Move around
cn_RS = Look around

Gameplay Tutorials:


Here I'm going to outline the key tutorials the game will teach you, just so you don't have to waste time in game looking at them and get familiar with them here:
Controlling your arms:
If you pick up one of the first few walkie talkies, controlling the positioning of your arms is introduced and it's a very simple topic. You use the left trigger to raise your left arm and the right trigger to raise your right arm. Once they're raised, you use the right stick to look around, and your arm will position itself where it's looking. For example, if you need to press a button to open a door, hold your arm out and look at the button to get your arm level with the button.
Climbing:
Now climbing isn't introduced until level 4 - Mountain, but it's definitely worth knowing about. If you hold your arms above your head and place them on top of a ledge, move the right stick down and you'll pull yourself on top of the ledge if your arms are wrapped over or just at the top of the ledge. This works the same for ledges higher up. You can jump up or across to higher or farther ledges and, as long as your hands or arms are over or just on the edge of the ledge, you can move the right stick down to pull yourself up on top of the ledge.

The Cheese Method:


Okay so now I'm going to introduce a method that can be used to skip the majority of the map most of the time if you feel so inclined, or it can even help you get up to some tricky spots. For at least three achievements that I can think of you have to make use of this method so give it some practice as it's very useful.
So essentially this cheese method will let you climb up massive walls which you'd not be able to get up otherwise. What you need to do is walk up to a wall with your arms raised up and jump towards the wall. Let go of one arm and start swinging your body. Tilt the camera so it's looking up at you. Position it directly in the centre of the screen so your body is swinging side to side without hitting the wall (if your camera isn't centred you might tilt a bit and hit the wall, killing your momentum). Once you've gathered momentum, at the pinnacle of your swing, try and get the hand that isn't already attached to the wall to grab onto the wall at a higher point. Once you're attached at a higher point, you can then let go of the wall with your other hand and raise it to the level you're on. Repeat until you're over the obstacle you're trying to get over.
This description is a bit confusing so below is a clip I made showing the use of the method to skip to the end of the Carry level.
Study it, master it, and you'll be flying through this game.
With the basics out of the way, let's head to the next page to start our adventure.
