Fix/timer drift & Touch up rooms

[Tyler-Lentz]

This was based on playtesting with gil anthony and I today in the lab

1. fix timer drift, so the 5 min timer is actually 5 mins
2. increase lighting in dark rooms so they are visible, may need to increase more for projector
3. reduce player deaths needed from 5 -> 3 b/c in our playtest phase 1 went on for way too long
4. make some of the 20x20 rooms a little less open in the center so that there are less super long hallways that stretch down the entire maze
