How to open the Steel Soul permadeath mode in Hollow Knight Silksong

To open and choose the Steel Soul permadeath mode in Hollow Knight Silksong, you have to use the famous Konami code. Go to the Extras menu and put the D-pad on your controller or the arrow keys on your keyboard to enter this code: Up, Down, Up, Down, Left, Right, Left, Right. This should make your screen flash once and the next save file that you start should have the option to select the Steel Soul permadeath mode.
Most enemies in Hollow Knight Silksong deal two pips of damage with a single hit, and it only gets worse when taking on the bosses. So the only way to complete this mode is by learning the enemy moves and actively chasing the masks to increase your health. Making a mistake and dying by accident deletes your save file, forcing you to restart the game from scratch.
