Spelunker Mode is a mode of Difficulty where players are extremely weak. A single strike received from any enemy in this mode will kill you. If you miss the classic 8-bit gaming days where games were extremely difficult, then this is the game mode for you. It is named after the NES game Spelunker where the slightest drop or touch of anything dangerous would lose a life.
How to Access
Spelunker Mode can be accessed by finding and helping Spelunker who is behind a rock in the top left corner or by typing in SPELUNKER in as a name right from the start.
A glitch in Spelunker mode allows you to freeze the world as well as all enemies and make Spelunker invincible to just about everything until the glitch is ended. See link below.
