It's a little to easy to die and I don't know if I got hit by the ghost or lost ammo but I could not do anything after that. I reloaded and try again and it looks like the ghost prevents me from shooting...There's a lot of information being sent to the player and not enough time to digest it. I recommend slowly introducing more enemies and allowing to level up maybe twice before throwing loads of enemies to give me a sense of "I can do this" type of deal
