Fun game, I find the high capacity elevators play negatively for you. They take longer to move, because they wait until they're full. I stuck to using normal elevators in straight vertical lines, then disperse high capacity ones randomly through parts of the hotel. Less complaints about them.
I'm just stuck on a black screen after pressing "Start Game". Click away and it shows the pause menu but nothing else happens. Usually deleting browser data works, but its not for this game.
Played this fine yesterday, today it either freezes at 1% loading (have to delete browser data), or it doesn't play at all when I login with my account.
Thought to myself Kongreate was missing something that I once loved about this place. This game gave me faith! I'll complete it when I get more patience.
