UPDATE
Changed the basepoints, so finding items is much more important for the total score.
You now start with 1000 basepoints, every second in the maze you lose 5 points, so without finding any items(almost impossible) you have +- 3 minutes and a half to complete the maze. The goal is therefor to find more items to gain more points.
For completing the maze and thus escaping you will be rewarded a 500 points bonus.
