07.The Clocktower - Initial Times Mechanic
钟楼最初的时钟机械
The Clocktower was probably the hardest level to get right and went through many iterations during development. Initially Chris looked at ways for the player to use time as a mechanic to give an extra dimension to the puzzles and build upon the Clocktower theme. The idea was that the level itself would change as the player winds time forward and backward, ivy vines growing and receding, the time of day changing and even the crow in the bird cage dying and coming back to life. However it proved too complex a design to implement successfully, with the player not only have to deal with puzzles set over several rooms, but also set over several time zones with a high possibility of finding themselves in a temporal paradox.
