What a creative and insanely clever game! Your use of text was so creative that I ended up forgetting it was the limitation at all.
The mix of music and sound effects along with the surreal environment of the visuals really just added to the great aesthetic that made the game all the more enjoyable, although I noticed that the music only came through the left side of my headphones, which was slightly distracting.
It's so hard to pick a favorite puzzle out of these as they were all so clever, but the one that had you going through wiki links to find the letter really stood out to me as well as the zoom one.
Great job!
