For those of you who would like some help for the first half of the riddle, the hints given below should be able to push you in the right direction. Give each level a serious try before you use these though. How will you make it through the other 15 levels if you can't even do the first 15 without help?
HINTS
1.) Look at the source code to help you figure out what to do.
2.) Think math.
3.) Making a cube two-dimensional would make it a...
4.) Use the equation in the source code to figure out what's missing.
5.) Don't over-think this one. Just make an acronym.
6.) How would a sloth or a bat see "6" as? Spelling helps. Try an anagram solver.
7.) There is a "1" missing from the sequence of numbers. Therefore it is...
8.) Just do what the equation says. What's different?
9.) Connect the hidden numbers. What could that number be referring to?
10.) Try typing in the only thing you see. It'll bring you somewhere. Need help still?
11.) Don't try to make sense of anything. Think anagram.
12.) Circumference divided by twice the radius equals.... But that still doesn't get you the irrational number that's shown. How do you get it then? Use a calculator and Google if you need them. Don't forget: multiplication doesn't always require symbols (ex: + , - ) to represent what is being multiplied.
13.) Think of where the two words are in comparison to each other.
14.) Those are subtraction signs in the title. The result may look familiar...
15.) Those are ranges in the source code...
