Text Walkthrough:


Welcome to the level 4, the mountain level. This is where your platforming skills really get put to the test. Walk forward and jump across to the platform, then jump across this to another platform. There are a bunch of platforms here in an S like shape that you have to traverse, so simply hold your arms out (in case you flub your jump) and jump across the platforms. If you fall off, there is a walkie talkie on the ground, and beside this is a ledge you can climb back up. Once you're done traversing these, you'll reach a wall with some ledges. This is where the game formally teaches you about pulling yourself up onto ledges by jumping, grabbing on, and looking down with the right stick to pull yourself up, but if you studied the general hints and tips you'll be a master at this by now. Use your new (old) skills to climb up the ledges, and once you're up top you'll see a red box car to your left, but we don't want to go there just yet. Instead, turn to the right and you'll see some ledges on the face of another wall. Jump across the two ledges, climb up to another one, then jump down and across two more platforms (make sure you jump to the furthest platform you can, you can try and risk jumping from the second furthest one, but if you fall you have to traverse the S platforms again). From this furthest platform, jump across to the next area and you'll see an opening to go inside the mountain, so walk on in.
In this area, we're going to go for the My Treasure achievement, which requires you to get 7 gems within the mountain and group them together. Now it is extremely dark in here, so you're going to have to bring a lantern with you. However, you can leave the lantern in some key places as the gems give off a green glow that you can kind of see. I'm going to go step by step of what I did to obtain this, and if you don't want to read a block of text, feel free to watch the video walkthrough.
Walk in and grab the lantern to the left. Once you have it, walk straight and you'll find gem 1/7. Drop the lantern, pick up the gem, and place it just to the right of this hole if you're facing it, which also happens to be at the bottom of a ramp. Walk up this ramp and veer slightly to the right at the top and you'll see gem 2/7 in an alcove to the left. Drop your lantern in between the two alcoves, pick up the gem, and backtrack to the ramp you just came up, go down, and place this gem beside the other one. Head back up the ramp back to your lantern and pick it up. Walk up to the right and you'll reach two more alcoves, and the one to the right contains gem 3/7. Drop your lantern in between the two alcoves and pick up this gem, backtrack to the ramp, head down and drop it on your gem pile. Work your way back to the lantern, pick it up, and turn around. Beside the ramp that goes to your gem pile is another ramp that goes up. Walk up it and veer slightly to the left, then walk forward and you'll come to a fork in the path. Drop your lantern here and leave it here. In the alcove to the right is gem 4/7. Pick it up, take it back to your pile, drop it off, then head back to your lantern. On your way, instead of going left towards your lantern, go to the right and follow the wall and you'll find gem 5/7. Before you head back, follow the right wall again and it'll lead you to another alcove with gem 6/7. Take it back to your pile, drop it off, and head back to drop them off. Pick up your lantern and head to the left, and in an alcove on the right is gem 7/7. Take this back to your pile and you'll unlock:

Again the text guide is going to be tough to follow, so if you're struggling either use the video walkthrough or take your lantern with you everywhere. Now that you have that done, head back outside and either traverse the platforms back to the box car or jump down and work your way back up. Either way, once you end up at the box car, head up to the ledge on the left and jump on top of it from here. Grab the wall and walk to the left to push the box car to the right so you can hop on the ledge that is on the right side where the tree is. Climb up to the tree and you'll see a rope around the tree. Grab it and jump off and you'll start swinging back and forth. Now you need to keep swinging back and forth at the peak of your arcs to build momentum to reach the other side. Make sure the arc on your swing is as big as you can get because, as you see in the video walkthrough, I didn't swing far enough, fell and couldn't do it again (well you technically could I guess if you managed to jump and catch the rope). If you successfully make it to the other side, you'll unlock:
AH, EO, EO, EO, EO, OOOOO! in Human Fall Flat

Once you're on the other side, you'll see a rock in the shape of a teeter-totter with it's left side up, and a box car up on a ledge behind it. Walk onto the teeter-totter and walk to the left side to raise up the right side, then walk up the right side and, before it falls, raise your arms and jump and grab the ledge. Walk up to the box car and push it until it falls off the cliff. Now head back to the teeter-totter and walk towards the left side of it and, before it falls, jump to the ledge on this side. Hop up to the next ledge and then raise your arms and jump across and grab on to the box car. Lift yourself up and walk across the box car, then up the steps and open the door to get into the house. Once inside the house, grab the two sets of speakers and throw them out the window to the left of you, unlocking:
Silent hours (Noisy neighbours) in Human Fall Flat

I threw the TV out the window too but you don't need to for the achievement. Now simply turn around and walk through the door and while you're falling, you'll unlock:
