Tak 2: The Staff of Dreams

In the tutorial level, you must have blue potions to go under or float over walls. When you reach the end of the level on ether side of the tutorial, you must have red and blue potions or you will die.

In the real world you will face Woodies, creatures made up of pieces of wood. Whenever you see a shaman, kill him because he will keep putting the Woodies back together after you've destroyed them.
