I was on Youtube one day watching videos when i found one called Super Mario Frustration. It was a video of some guy playing a ROM hack of Super Mario called Super Mario Forever. It looked insanely hard so I found and downloaded it. I don't know if any of you have played it, but if you have I'm sure you will agree that it is one of the hardest games you have ever played. I died at least 50 times before i got past the first few jumps. If you haven't played it, it's worth trying. You will also have to download an NES converter to play the game, if you decide to download the game and try it.
