I'm currently on level 23. Here is a guide to where I am from level 19.
Level 19 is pretty tricky, but there is a way to figure out the password.
Here's a hint: Download the picture and increase the contrast. When you figure out the username and password, click
the fingernail.
More hint: The top set of letters is the username, the bottom the password. However, both are encoded.
More hint: Look at the direction the finger is pointing and think about the title, "he moved it in the right
direction."
Spoiler: username : password = unfair : riddle
Level 20 is easy.
Hint: The only thing important to the level is the symbolic writing in the middle.
More hint: Those symbols are a Windows font.
More hint: The font is Wingdings.
Spoiler: username : password = really : unfair
Level 21:
This level took me almost 2 days.
Hint: Alpha means beginning. Omega means end.
More hint: Replace again.htm with blue.jpg
More hint: Combine everything together to make a map.
More hint: The path spells out the username and password.
Semi-spoiler: Replace again.htm with solution.jpg
Spoiler: username : password = making : progress
Level 22 is simple.
Hint: There is no clicking or extra thinking involved. The solution is right in front of you. Read the sentence in the
picture.
Spoiler: Change banana.htm to unexpected.htm
Level 23 is, well, I haven't beaten it...yet.
I changed unexpected.htm to pixel.htm and got a message saying "ya, I'm small and red, zoom for
me."
Hmm...*deep thoughts*
