This game is really good so far! I like the plot and the puzzles, although I'm pretty sure I'm missing something. Where exactly is the ballroom? And is the clock time the combination for one of the locked doors? Other than that I'm having a good time and I can't wait to finish the demo! Great job!
The ballroom is at the end of the right hand hallway, and to get all the combinations you need to use the time in conjunction with the amount of time late in the journals. The third journal piece is in one of the rooms you'll unlock
Hope this helps!
