Spacechem

Oh the old dorm days with Alice: Madness Returns on nightmare difficulty with my roommate. Oh all the rage that was release those nights! Fond memories.

cs go for sure.

Ghost'n Goblins. I'm not sure I even saw level 2.
Also +1 for Super Hexagon !

Super Meat Boy or Geometry Dash (Damn keyboard on SMB x_X)

I wanna be the boshy
thy it I got a cancer from it

Bad Rats.

Maybe UN Squadron on the Super Nintendo... But I really enjoyed it because of its difficulty.

Almost every game, im not a really good player
right now, i would say Road not taken because it gives you a false sense of achievement, not backing away and admit my losses always leaves me without magic or life or whatever that was.
also Alien Isolation, because of unpredictable ai.

Surgeon Simulator. I can't grab anything :((

Mr. Bones for Sega Saturn. The Icy Lake level, specially.

life, playing for over 30 years now...

Bad Rats

The Binding of Isaac

Myth could make your hair grey

I never did beat Blaster Master on the nes.

Contra

Space Chem and Great Permutator. cant choose which...

I Want To Be the Guy: Gaiden. Nuff said.

Fire Emblem for the GBA. The game itself is not very hard, the hard part is to everyone to survive! And I made!...till the very last level.
I tried, don't judge me!
