Very hard game. As others pointed out, at the start it was difficult to find what exactly to do. (for example: took my a while before I knew you had to operate the elvator with w/s, I tried clicking the buttons)
Once you know what to do, it is a fun game to play :D Timers are a little short maybe, but it is probably intentional :D
Well done. (just wondering, is there a way to win the game? or does it always end with the hotel manager?)
