Yeah, I wish I could get into this game, love the idea and the whole Luigi's Mansion flair, but sadly, I can't get past Floor 1.
I am playing on normal, and I'm always get ganged up on by 3-4 ghosts at once, all spread out in a way that makes flashing them all impossible in these narrow hallways. I am able to beat about 10 rooms before I get defeated, but then there's no way to save the game, meaning you lose aaaaall the progress as soon as you are defeated once, which is inevitable.
So yeah, great game, but sadly most of the content seems to be locked behind difficulty that is just beyond me.
