How to reach the island at the end of the forest in candy box 2

You should enchant your gloves by throwing chocolate bars into the well. Pink gloves are great for the forest (they give you health regen). Also, you should kill the monkey wizard in the cave for a better weapon. Enchanting and using his staff should make the forest level easy, especially if you already have 220 health.

The forest is a roadblock at first but if you can clear out the cave it'll be easy.

Wearing the Boots of introspection will prevent you from moving forward while touching the floor. You'll need to jump in order to go forward (while in the air) and that will make you able to reach the end of the level.
