Wow, just wow. Played through the game, only to find out on the 6th stage the add-ons I purchased weren't equipped. Make sure to tick the box on the left after purchasing to equip.
The pieces are often placed as far away as possible from the spot they fit, usually on the other side of the board. Like top left corner piece would be on the bottom right. You're welcome.
Put the Amenities on the RIGHT side of the hotel for two reasons: People will have to walk to and from the Amenity, adding time to the day. This also makes Room Service's walk from the elevator a maximum of two rooms.
OK I figured this out: If your customers are frequently trashing their rooms it's because they do not have enough to do or dislike the room. Give them a good room, have lots of amenities available; they'll be less likely to trash the room and spend more time about the hotel (therefore lengthening the day and getting more cleanup time in)
In agreement with Metholus: If there are no customers for the day but there is cleanup work to be done, then allow some of that to happen otherwise skip the day. Room service time either needs extension or the foot speed of the room service people need increasing. Overall all employees could be faster. Very difficult to get comments on room service and have a mostly clean hotel at the end of the day.
Re: Hums: You have: Donut Brick Lemon Rose. The numbers correspond to the position of the letter you need to work with. Find the big grin and tickle its nose with an item.
Here's how to make a mess of diamonds for your pick up pleasure sound: Have max jump and rebound gun with bounce off enemies strong enough to destroy chapter 7's lasers in one hit and go to chapter 7. Find the section with three red horizontal lasers, where X-Ray used to be. Go down below where the hidden red diamond was and jump from the low platform into the secret repeatedly. Go back to the lasers and you'll notice one of them is significantly brighter than the others. Hit it with rebound shot to detonate them all at once and have that pile of diamonds pickup sound. You'll also have a lot of pots on the platform above it, and they stack on a space too. Here's a screenshot after doing 50 such jumps although it's overkill to do that many: http://i.imgur.com/Qa4qZ.png
@restingcrowd: You need to lose the game to submit the score, though I agree with you in the sense that it's bad design to allow a player to end the game without a score submission.
