I'm too lazy to find out for myself so I am here to ask you guys about the differences between the difficulties.

The sole difference is how much damage the enemies hit you for. They should have the same amount of health. The difference then becomes apparent in where you have to pick up bananas to heal yourself, and to avoid certain tiny speed strats normally done in Easy to preserve health.

Sabor was annoying as hell at first, playing the game through on hardest difficulty.

But I soon learned an easy way to beat him...just use the long stab, jump over him if he does come at you, repeat.
