What are the most frustrating parts in games? What I mean by frustrating is you're able to beat most of the game pretty easily up until one part.
For me it was in Donkey Kong 64 when you needed the N64 coin and you had to play the Donkey Kong arcade game. I had to have tried it at least 100 times. I could just never do it. I could usually beat the first level pretty easily, but that one with the springs just drove me crazy. I stopped playing Dk64 just because of that part. I eventually beat it, but it just took so much of my time.
