Unlock True Ending cheats for 1001 Spikes

Unlock True Ending

When you have possession of the Key of Serpentis play level 10-7, 'Jokulkyrkja', in Antarctica. If you then jump on the platform with the strange serpent symbol it will lower you into a Boss fight. Defeat the boss by throwing knives at the crystals on the ceiling in order to break each section of the dragon platform you are riding on. After the Boss has been defeated you will unlock Antarctica for ALL the characters, Jim Hawkins, and the true ending.
