Randovania

Randovania is a program for randomizing multiple aspects of several games, making a fresh experience out of the familiar.

Depending on the game, users can randomize where items appear, how areas connect to each other, and more. And after things are changed, Randovania checks each randomized game to make sure it's beatable. Experienced players can also turn up the difficulty by making glitches and unintended tricks potentially required to win. (Randovania will not expect players to use glitches to win otherwise.)
