New Power: Energize - Reconstruct destroyed areas of the environment to create a path and rush through it before it vanishes.
New high pace: The new trap challenge - The Prince and Elika will face more cunning foes, cleverer traps and level design, adding more to the difficulty level in over 3 hours of gameplay.
