Spoiler

Quest 1: 2+2,
Obvious.
Quest 2: Cow, Pig, Chicken, Iceland, Dog, Cat
One of these things just doesn't belong here
Quest 3: Right
Not really.
Quest 4: The password is not hidden
The answer is in the question.
Quest 5:
Highlight the page.
Quest 6: The source
Right click, and look at the source code. You will see some ASCII art of a well known cartoon character. The answer is this character's name.
Quest 7: Starts with f ends with uck.
The fire department owns these.
Quest 8: 3^3
3 * 3 * 3
Quest 9: 2x-4=2+4(8/2):
Solve for x
Quest 10: #0000FF
HTML/Hex color code (google it if you don't know what it means)
Quest 11: Red
Find the HTML/Hex color code for red.
Quest 12: Times previous quest
What number was the previous quest? Multiply that with this quest number.
Quest 13: True
Think about this with boolean values in mind. If something is True, then the "value" is 1, if something is False, then the "value" is 0. (Goes along the same lines of binary, 1 means on/true, 0 means off/false)
Quest 14: sdrawkcab ton si rewsna ehT
Read it backwards and remember quest 4.
Quest 15: The Force
This is the first part of a line said by Darth Vader in the Star Wars movie. A well known line.
Quest 16: This is not the answer
itwo
This is the answer is the answer to this, but take note of the letters given to you.
Quest 17: Ring
Another word for ring? (Also a well known Xbox game)
Quest 18: Swiss
Something Swiss that is not cheese. (Not a swiss invention, however)
Quest 19: The answer.
Think of "The Hitchhiker's Guide to the Galaxy"
Quest 20: Friday
Think of part of the lyrics to the Song Friday by Rebecca Black. (Same word repeated three times)
Quest 21: Saturday
Once again, think of the lyrics to the song Friday. Saturday comes _ ?
Quest 22: ABCDEFGHIJKLMNOPQSRTUVWXYZ
What is the problem with this alphabet? (Keep the answer as short as possible)
Quest 23: 1/0
Dividing by 0 is what?
Quest 24: 1337
Use 1337-5p34k (Leet speak) What does 1337 (leet) really mean?
Quest 25: How to triforce
If I'm not mistaken, this is a joke that originated (of course) online where there was a .bat file that supposedly contained the triforce symbol from Zelda. However, what it really did was something else. What it did is the answer (Very difficult to give a better hint)
Quest 26: Gur pnxr vf n yvr
They have played with the letters (very simple cryptic message that has to do with the game Portal)
Quest 27: What if Zelda was a girl?
The main protagonist in the Zelda games is male. Zelda is the princess whom Link (the protagonist) wants to save.
Quest 28:
I don't undestand this one, I found the answer online. I thought it was morse, but the numbers don't match, 1728 is the answer.
Quest 29: /.. (etc)
Initially I thought it was morse, but like 28, I needed help with this one. 21 is the answer.
Quest 30: Money
Is the root of all what?
Quest 31: Sharing
A well known saying.
Quest 32: 5f4dcc3b5aa765d61d8327deb882cf99
If this was your _ , I don't think anyone would be able to guess it thus not being able to access your account.
Quest 33: Bear in bed
Crappy meme joke that starts with Nope.
Quest 34: lol+lol
Written giggle/laughter often considered feminine
Quest 35: Friday - Sunday
Friday is x amount of days different than sunday? (Friday is [in Norway] weekday #5 and sunday is weekday #7) The answer is in form of a number
Quest 36: A
1A
111A
311A
13211A
111312211A
There is a logic in the numbers. If you think about it you may get it, if not, check the post with the answer.
Quest 37: Feb 01 1970
Unix Timecode at GMT 06:00:00 (Find the number out yourself, Google it)
Quest 38: A fatd kmskfdr
Like earlier, cryptic message. I'll give you some of the letters
A = I
f = L
d = E
r = S
Quest 39: ghjkl
Google dvorak Keyboard and see what it would be if you used that keyboard layout.
Quest 40: AHGDSGEGSGSHAASGSHAGSHASSGSDGDSAFSHSHFSJHFGHFSASGDSGFDSGFSAGFSAGSFGSFDGSGDGASFDSGDSGSDSAGDSFS
Well isn't this just a bunch of nonsense
Quest 41: Y_U G_T T_
What do you have to do?
Quest 42: Z O T T F F S _ _ _
There is logic to it. All of the letters in the answer are different though (and separated by a blank space)
Quest 43: 696867686969696868686969693269686768696969696868696867
There are two parts to this. Take number #2 minus number #1.
(It would start like this; 321333)
If you have a phone that still makes the sound when you hit the number, you'll hear the song and have your answer.
Quest 44:
33 36 _
_ 61.08 67.58
E N _
-276.02 _ 366.48
I was thinking coordinated when I saw this, but didn't work out for me. If you have any idea what it is, please let me know. I know the answer due to some Google searching, but I don't know why it is so.
Stuck at 45.

 

Yeah I'm stuck at the second one. ;-; It's totally Greenland...

 

The answer is right in front of you. ;D

 

OOOOOH YEAAAAHH, I'm such a smarty. Now to figure out the blank screen...

Edit: Derp

 

This is quite entertaining. I'm currently at 13.

 

...I'm still stuck on question 2..

 

Ruining it:

Iceland

 

Did you get it? If not, I can tell you.
I'll be nice and tell anyone whatever answers I remember if they need it. Lol.

Again, the answer is right in front of you.
Don't think to hard about it, just look.

EDIT: dammit noroz

 

ok now i'm on the blank screen..

 

Well, I'm at 45 and I'm stuuuuuumped. (Google is very helpful when I'm completely stuck, but not this time)

 

I feel like a moron. .-.

I'm currently stuck on 4.

EDIT: herp derp

 

If this is the question I think it is, it's not blank.

45 is just
goddammit
My friend got to 48 somehow

What's 4?

 

At q 4, it specifically tells you the password.

 

Quest 6, someone please assist. The Source? What ever does that mean? Google offers no assistance. I wonder why not, how old is this. Is it new? Ehm... stuck...
I would have wanted to solve this on my own, but...

 

You might wanna take a look at the site source.

 

I tried that! The Hard Game. I tried. It doesn't work. Or am I doing it wrong...

 

Right click, View Page source? Look for ASCII art

 

I... think this is new? idk.
The question is trolling, follow Noroz's advice. If you still can't get it, we'll tell.

EDIT:
Homer

 

Got it, much obliged.
