Pipe Maze.

Mog-Rat

Have you checked behind the cushion on the couch?

Did you notice the line behind the couch?

You need to use ALL the pieces of tube to get the rat to the end

You also need another component which fits in the slot to the bottom right

turn left 2 times while you are big and look under the pillow, after turning on the lamp light.

everything in the first three rooms, go the genetic code, done the maze, got the womp rat, and in the forth room Ive got a knife. All three rooms are lit up (I have the powered up power core), but I have no Idea where to go from here :(

You can enter more than one number into the combo lock. There is another code hidden somewhere

You need another four digit number for the machine that gave you the knife. Look around in the small rooms. It's written in green.

you are out

three panels and a boiler

looking behind the couch (although I knew that I had to slice something on the couch with the knife, I didn't know where to slice).

I would never have been able to figure out the pipe code without help because it looked like 515

1. The couch. Man, I hate when these games include an arbitrary hot spot which, when clicked, suddenly shift perspective so I can do what I actually wanted to do. I have a knife, I want to cut that armchair in pieces, but I cannot until I click at the spot approximately 2 inches right of the chair. What? Silly, unintuitive and unnecessary.
2. The rat-maze code. OK, perhaps you find this clever, I find it gimmicky and illogical.
3. For some reason the game didn't let me do the correct thing in the end, i.e. put the core in the cube. I had opened and closed the iris like an idiot the core didn't want to go in. I give up, wander around more a little bit, try to find some more obscure 4-number combos (like, I dunno, the number of bricks times the number of arrows) and finally read the walkthrough to realize I have been trying the correct thing all along. VERY frustrating.

"A solid brick wall, no exit here"

If you know the code numbers that give you the knife and the remote control, you can bypass most of the puzzles, because the cube doesn't care whether you've charged the power cell.
Specific steps:

screwdriver, hot water jar, a glass of hot water, a circular plate with buttons, a smoking fetus-like-thingy, a smoking tube, another tube that shows yellow on the window, and 3 puzzle pieces.

how the heck can you get 5151 out of the pipes?? they don't make the second "1"

The power gauge on the right side of the maze forms the second 1.

You CAN take a Mog-Rat with you; you get an infinate supply!

to remove the panel? Even though I got it loose by using the screwdriver on the four little screws, every time I use the screwdriver on the big screw it replays the panel-dropping-to-the-floor animation.

the other two square chips?

when opend to the brick wall close it use the key again THEN there will be a light around it then open then you are really FREE

5151 and not sure where to place the fully charged power core
