Monkey GO Happy - Maze

Pick up the Mini Monkey and screw from the ground, and head to the room on the left which has a helpful map of the whole maze.

X and Q Paths:
Pick up the screw from this map room.
Go left to a room where a large round socket is sparking, and pick up another screw.
Then go forward to a room with clues on the left and right walls, and pick up another screw.
Move forward to a room with a broken pipe, and pick up another screw.
Move forward to a room with a map, a screw and a wheel with a pointer at the top.
Move right to a room with an X on the front wall and a lever on the right, as well as a Mini Monkey and a screw.

Move left, back all the way, and then right through the starting room to the second map room. Pick up a screw from it.
Move right to a room with a sparking rectangular socket, and pick up the (well-hidden) screw on the left doorframe.
Move forward to another map room with a device marked A, as well as a Mini Monkey, screw and wheel.
Move left to the Q room, and take the screw on the wall.
Backtrack to the starting room (and check that you have a total of 11 screws, 3 monkeys and 2 wheels).

S and H paths:
From the starting room, move forward to a room with clues on the walls and a robot who wants 31 screws, and pick up a screw from the floor.
Move forward to a map room with a screw on the floor.
Move right to a room that has a clue on the wall and a screw in the corner (very easy to miss!).
Move forward to another map room with a screw on the floor.
Move left to another room with a wall clue, and pick up the screw and wheel.
Move forward to the S room that has an unusual clue on the right wall, and pick up the screw from the floor.
Move back and right twice to a room with a round hole marked with a sideways B and a screw on the floor.
Move right to a room with a B device, a clue on the right wall, and a screw on the floor.
Move forward to a map room, and take the screw and wheel.
Move left to a broken pipe room with a screw on the floor.
Move left to the H room, and take the Mini Monkey and screw from the floor.

Backtrack to the last room on the map (marked with four dots), which has four round things protruding from the wall, as well as a device missing a handle next to the trapdoor on the floor. Pick up the screw on the floor (and check that you have a total of 23 screws, 4 monkeys and 4 wheels).

Use all 4 wheels on the wall in the four-dot room, and use the clues throughout the maze to unlock the letter walls.

Move right and down to find the clue for X (left, up, down, right). Following that clue, you should click the wheels to point in the
←↑
↓→
directions, and then proceed to the X room to pull its lever.

Inside, there's a rectangular fuse, a screw and a Mini Monkey.

On the way back, you spot the clue for S:
><
^V

So adjust the wheels accordingly and pull the lever in the S room to get the screw, round pipe piece and Mini Monkey.

The room next to it has the Q clue:
V>
<^
and opening the Q room gets you a screw, pipe piece and Mini Monkey.

You also spot the H clue near the map room:
^V
><
and opening the H room gets you a screw, round fuse and Mini Monkey.

Moving right from the H room, fix the broken pipe by using a piece on it, and a panel on the right opens up, revealing a screw.

Then make your way towards the X room and fix the other pipe to get another screw.

Then go back (south) twice and use the round fuse on the socket to get another screw.

Then go right all the way and fix the other socket to get the last screw.

Now that you have 31 screws, use them on the robot in the room just ahead of the starting one.

He walks away leaving a button (that looks more like a knob) behind.

Use the button on the hole along the H path, and use two other clues in the maze to figure out how to activate it.

The same turned-B marking appears over four crossed circle symbols, and a clue along the H path tells you that those symbols mean S.

In this case, S stands for South, so you should make each of the four wheels point down.

Then click the button/knob to turn it. The panel opens up so you can take a lever, two wheels with lit quadrants and a Mini Monkey.

Use the quadrant wheels on the A and B devices (along the Q and H paths), and use the clues from the maze to turn them correctly.

According to the clue along the X path, the A and B wheels should be lit in the upper-right and lower-left.

So click the A wheel once and the B wheel thrice to rotate them into place.

We're not done with this puzzle yet! Use the lever on the device in the wheel (four-dots) room, and then use the clues from the maze to turn those four wheels correctly.

According to the clue in the S room, the four crossed squares on the wall each signify N.

So turn the wheels to point North, or up.

Then push the lever to open the trapdoor. A (different) robot pops up, ending the game. But you can still pick up the last Mini Monkey next to him before moving on.

The bonus clue for Stage 112 is (2 lines, bar, dot) = 5.
