Hardest game you have played?

Super Hexagon

Probably Super Meat Boy, I've played a lot of hard games but this one was the worst one for me

Dustforce by far, I've played BoI/Super Hexagon/Super MeatBoy/Spelunky whatever hard platformer you can think off. Dustforce is the hardest, and my favorite.

I wanna be the guy or VVVVVVV.

Quake I multiplayer after about +10 years since i stop playing often Quake.

I Wanna Be the Guy, for sure.

S.T.A.L.K.E.R. for personal reasons lol

Everyone who says IWBTG has not played i want to be the boshy (and probably not beaten IWBTG)

Cuddle Truck, no doubt about it. Hardest game I've ever played.

Der Langrisser was hard, especially if you cranked up the difficulty by switching onto the opposing side several times through the game, but the horribly tricky platforming and puzzles of alundra on the ps1 made it the hardest I played

N+ on PSP

Super meat boy, Dark Souls.

First Rayman from 1995.

Super mario bros frustration
Despite being a hacked rom, it makes any other game easy mode

Super hexagon.

They Bleed Pixels is not that easy.

cave story + with good ending :)

Serious Sam: The Second Encounter. That Cathedral music :>

BATMAN!!!

Magicka, the game is completly unfair sometimes.

They Bleed Pixels, Electronic Super Joy, Waveform (especially when trying to get 100%, which I did not and will never), binding of isaac.

SotS: The Pit on Insane. The fact that there are achievements for it hurts me very much.
