Arrrrrggghhhhhh! = FlaiL
One of the things I hate most is when a game is overly complicated or too complex for the message it is trying to convey *cough* MGS series!*cough*. The wonderful people of Make Us Of.com have compiled a list of the hardest games and I can [un]happily tell you that these game are awesome at killing your time as well as your soul.
More delights after the jump.
5. La Mulana
You’re an adventurer, and armed with nothing but a whip, you choose to invade the tomb of La Mulana. Like always, these tombs are far from empty, and trespassers are not particulary celebrated.
There are many items to be found in the game, many of which will contribute to the story, and some that will grant you additional abilities and weapons.
Remarkable for this 2D platformer, is that the story is non-linear. Yes, the ending will always be the same - if you manage to reach it - but there are tons of different ways to get there.
The game was originally released in Japanese, but an English patch was made available by Ian Kelley of AGTP. So you’ll need to download and install both the original game and the English patch.
4. World’s Hardest Game #2
The fourth place is taken by a flash game - the World’s Hardest Game 2 (talking about paradoxes).
The game looks ridiculously simple, but don’t be fooled; many brave men and women went down because of carelessness.
You play with the red square. Your objective is to grab all the coins and return to one of the green patches. There’s only one obstacle; the little blue balls. Touch those and you’re done for.
Easy, right?
The problem is that these little blue balls constantly move around, which creates a deadly maze that you need to get through.
Instead of showing you the number of lives you’ve got left, the game chooses to mock you with the number of lives you’ve lost so far. Play through all fifty insane levels, and you’ll hold a name of honor.
If you enjoyed playing this game, you should also check out the first game of the series.
3. Japanese Mario Kitten (dl) 
Our bronze medal goes to this Japanese Mario-like game.
The game has a high degree of randomness, which takes the difficulty to a whole new level, so don’t be surprised when you hit invisible bricks or get killed by the clouds from time to time.
Many people claim that because of this, completing it is more a matter of memory than of skill. But whatever the cause, the difficulty of this game is undeniable.
The game can be played out of your browser on this page, or you can download it here.
2. FLaiL 
Being the second hardest game available, FLaiL receives the silver medal.
FLaiL is an acrobatic 2D platformer, in which you need to hike, jump and even fly accross the level to reach a red beam. The difficulty of this game lies not in any randomness, but - as you can see in the screenshot below - in the insanity of the level designs. Even the tutorials are pretty hard, and it doesn’t get any easier.
Play through the 80 available stages by yourself or in co-operation mode. It’s also possible to add a third player, who then occupies himself with dropping bombs to make it even more difficult!
1. I Wanna Be The Guy 
By far the hardest game ever made, I Wanna Be The Guy.
I admit, if you manage to finish this game, you’ll be one hell of a guy.
You’re playing the role of Kid, who’s on the dangerous quest of becoming a guy. The game is frustrating at times, but wonderfully designed and hosts several cool references to old school classics - like the tetris level.
This game manages to combine utterly insane level designs with bits of randomness. You see the screenshot above? Chances are pretty good that a few of those spikes will try to attack you in mid-air.
Similar to Japanese Mario Kitten, remembering the oddities of each level plays at least as big of a role as your skill. However, if you manage to beat this game, you will be amongst the elite few.
If there are any games which you consider to be the hardest games in the whole world, please let us know in the comments what they are.
