I should be weak and frail in the beginning, gain some abilities that make me awesome for awhile until I come upon tougher enemies and I need to gain more abilities

I always try to find alternate ways to move around and defeat the enemy.

A friend of mine had described it as a "game where the enemy can pose as any object"

The enemies in the game are my favorite in terms of their style and abilities

This game was fun for the first few hours, then enemies became too hard, puzzles were impossible, objective way-points were nowhere to be found

The poltergeist monsters are possibly the coolest and best-designed enemy I've seen in a first-person shooter.
