I finally completed it. Picross had me for a while, I was right in the middle of Hotel Dusk when I got Picross for Valentine's day gift. Needless to say... Picross got me hooked... darn puzzles. But as soon as I was done, I fired up Hotel and started from where I left off which wasn't too hard.
I actually remember what it was... but anyway, I like the whole game. I just don't like clicking through it whenever you know you messed up. TEXT TEXT TEXT, OH MORE TEXT, THEN finally questioning the character again.
I certainly didn't like ONE thing where you wonder about the laundry cart. That is SO vague there's no other clue besides oh "Jeff came out of that hallway". :\ But that's like the ONLY time I ever looked up on gamefaqs for this game. Amazingly enough I managed to solve Helen's puzzle after a few tries, took me a while to figure out what she meant by ONE COIN ONLY.
There's nowhere I can't reach.
