Ice column puzzle in Alundra was one of the first instances where I can remember getting really frustrated. Some of the dream puzzles were also tough.

No, wait, actually the first game I remember getting stuck was E.T. on the Atari 2600. I don't think I ever figured out the point of the game. Yeah, what the heck is going on there?

Portal 2 had a stage that really frustrated me, as well. Even though I was determined not to look up solutions, I had to for this one. It was one of the more story-driven levels and you had to fall from high up through a portal on the floor.
One of the Edna and Harvey video games frustrated me enough that I never went back. Part of that was because you had to go through so many loading screens, though, when searching for clues. I got tired of that. Really interesting games but in this instance, I had about 5 different zones to search.
