It has a lot of backtracking, feels a bit repetitive, and you need to use hundreds of shots to kill a boss. Not to mention that you can't start out on a real difficulty, so your first playthrough is likely to be broken easy. It's less FPA than the previous, and more of a mindless shooter, as all the puzzles are very easy.
