If you want a challenge, I’d recommend googling The Legend of Zelda: Beta Quest. It’s a ROM hack where the load trigger table (that is, the table that contains what door leads to what scene) is randomized using the save file name. The only way to win is to get to the final Ganon fight and defeat him, and there is a way to lose since there’s this test area where Link can’t move and is then killed by some armored enemies, and the load trigger table can sometimes open that up.
