February 2012 : Treasure Hunter Competition

[micronexer97]

All right, I've made some improvements and now I might (might!) have scored optimal. I don't want to give too much away, but I will say that after my initial score of 60, I earned scores of 1?1, 1?4, 1?6, 1?7, and my current best, 1!1 (where ? and ! each represent a digit from 0 to 9). Also, in my best solution, Chip reached the exit with the bare minimum time left (1/5 of a second).

Hmm... 4(5) + 4(10) + 5(5) + 20 = 105... I think I can assume ?=1 and !=2
