Adds a configurable time limit to the game, which kills you in dramatic fashion after expiring. The time remaining is displayed at the top-center of the screen, and is lowered slightly to be compatible with Dregu's In-game timer with killcount.
The default time limit is 2 hours, but can be configured in the lifetime.lua file in the mod's folder:

After opening this file in any text editor, simply change the number of hours, minutes, seconds and frames to the desired values. (60 frames = 1 second)
