We did it! We finally solved the invisible maze! In case anyone else wants to try, I'll reproduce our steps here.
Here's the maze:
- All walls except for the outer ones are thin, invisible glass. There is no way to know there's a wall there until you touch it.
- If you touch a wall, you lose. No retries.
- The inside is divided into rectangular "rooms", all of which are the same size. We don't know how many there are, though.
- From every room, you can get to the eight surrounding rooms (up/down, left/right, and diagonally). Unless there's a wall in the way, of course.
Here's how we found our way through:
- We tried to divine the answers from a dairy product prepared in dark hardwood.
- We searched for hints in a global information network for people's cats and dogs.
- We perused the text of a Nordic heroic poem.
- We asked someone extremely knowledgeable about the types of human perception.
- We enlisted the help of a dead person with combat experience.
- We interviewed people who make their living selling German cars.
- We took advantage of the power of the Sun's radiation.
- We employed people with telepathic powers.
- We visited a distant Norwegian island in search for clues.
- Finally, we inspected our molars to find hidden information.
Can you follow our footsteps and beat the invisible maze?
Note: some of these things are made up. (In case it wasn't clear from step 2 already)
Edit: I'll give up the first line, since looking at this again that one turned out nigh-impossible when you don't know the objective. The answer to the first line is
The other answers make a bit more sense, I promise.
One line has already been solved correctly by Astralbee:
