On the special seed selection menu, it is possible to remove a discovered seed by focusing it and pressing Q+E+Tab on keyboard or LB+RB+X on controller.

Selecting multiple modes at once is also possible. Pressing Q / Left Bumper during character selection will bring up the Easter Egg Section, in which any previously unlocked game mode can be selected.

Once a special seed has been entered, it will be permanently unlocked without needing to enter the code again.

On the PC version pressing the I, O, and U keys during seed entry will replace them with 1, 0, and V respectively.

All alphanumeric characters are accepted except for 5, I, O, and U.

Special seeds do not affect level generation.

Except for some special seeds, inputting a seed will cause the 'no trophies' mark to appear.

Seeds will be the same on every platform as long as the game version is also the same.
