 The initial hours of the game , before the player started to acquire some of the more potent powers , were considered to be difficult and may be off @-@ putting to some . Tom Bramwell of Eurogamer noted the remainder of the game continues to have some difficult sections , such as sections where the player must defend a moving target against a large number of foes , and considered these to be " repetitive and overlong " . Bramwell further commented that the electrical powers in the game are simply electricity @-@ based reimaginings of standard video game weapon archetypes , such as shotguns and sniper rifles , and , with this awareness , leaves the difficulty of the game up to the enemy placement during encounters . The game is also considered to be rough around the edges in technical execution , with the lack of anti @-@ aliasing and occasional " pop @-@ in " rendering , as well as drops in frame rates when there was a significant amount of action on the screen .
