31. Get on the lift and use the up button to take it to the second floor. Open the little metal box and take the rope.

32. Continue taking the elevator up to the top floor.

33. There’s a lot going on here. Step off the elevator. I’ve highlighted important items in the room.

34. First off, inspect the diving helmet. Take the skull key from inside.

35. Use the skull key to unlock the chest. Take the golden star disc and tap on the spider web if you’re trying to get the Spy-der Web achievement.

36. Zoom in on the lever on the wall and pull it down to drop the ladder.

37. And last, read the lighthouse keeper’s journal. Focus on the symbols and the numbers they represent. We’ll need it later.

38. Go back down and outside. Look at the left side of the lighthouse again. The ladder is near the wooden box. Climb up the ladder and pull the blinds closed.

39. Go back inside the lighthouse and notice the numbers on the closed blinds. Note them down, because they’re different each game.

40. Leave the lighthouse and go back to the beach. While here, look up to the right at Gunther the bird and notice that the tree above him looks familiar.

41. Go back to the elevator and take it to floor 0. Head through the left doorway to get outside. Take the right path, behind the stone sculpture.

42. Zoom in on the tree and the stump. Then tie the rope to the stump. You can also get the Boing, Boing, Boing achievement here by playing with the TV antenna 10 times quickly.

43. Climb down the rope to meet Gunther the bird. Pull the peg out to drop the net. And if you’re trying for the Gasbag with Gunther achievement, make sure to interact with Gunther until you run out of text responses.

44. Go back to the beach and inspect the contents of the net. Take the stone artifact and also grab the net.

45. Go to the boat. Zoom in on the hook and attach the fishing net.

Can’t find chapter5

parivesh sharma

I don’t understand the spider web thing, nothing happning on mine.


Hi yeah, you said the final blueprint piece was under the jet pack, but I’m still missing a piece? What’s the other location for the 5 clearance blueprint piece?

Conrad Uno

Hey, same for me but I’ve just found it! I was also missing the clubs key from the hallway box which i know i got in ch4. So went back inside Ruby’s house upstairs to study and over on the shelves that the cat knocked was missing blueprint and club key. Maybe it was the update, just glad i can carry on. Hope it works for you too


Same here.


So I finished all the chapters and I think you all need to follow the cat footprints the upstairs part of Ruby’s house. I did that in chapter four and got all the blueprints.


how the f? I found only one blueprint at the start of chapter 5 like you. But I seem to have one missing still.


I was missing one too. Found it back in the house in the room with the phone and the phonograph. On a shelf by the red lever.


Thanks for the tip. I found the missing blueprint piece there too.


I got the bird on the log with a fish before I knew to take a fish to the cat. I keep trying to get another fish, but a bird flies away with it every time. I have the key for the pink -2 room, but my code won’t work and I’m assuming it’s because I haven’t given the cat the fish yet. Do I have to reset the whole game now?

I can’t move the spring on the security pad in floor -1


Same here.

Shubham Trivedi

I can’t find Spade Key


Me either


How do you get to the waterfall?


What is the trick to the puzzle to open the waterfall?


This is a hard one to crack I am still stuck on this


Is there a trick for the floor puzzle beyond matching it to the pattern inside the box? I’ve definitely matched mine but no box pops up for the key.


Check second from bottom tile, rotate it a little. It was a problem in my case


Has anyone solved the puzzle behind the waterfall?


Also stuck here. I did the puzzle and nothing happened.


Check second from bottom tile, rotate it a little. It was a problem in my case

What is actually behind the middle door with the gold handle? It’s never opened throughout the entire game or did I miss something?comment image


Hi, I do not appear to have the rope, despite reading this I cannot find it, where is it?

Charlotte Evers

Have you found this yet? I’m missing it!


I just saw the answer to my question. Thanks!


where’s the floating box? I can’t seem to find it.

Ray snowden

I’m missing a ruby. I thought I got them all but one is still missing. Is there 3 or 4 Ruby’s? I’m stuck.


The one I’m missing is the top one. Where is this located? When I dropped the others in it went to its place.


Where do we get the second stone


Hi, I’ve started chapter 5 but I can’t find the lighthouse?
