Man, I don't know how this will end, but you made a great maze. The flag is either in a1 or way down by the start and you've got some giant balls. 50/50 shot in how to get to a1.
b3 to a3
a3 to a2
a2 to a1?
I really like my maze, but I wish you had hit a few more of the walls so the game would be a little closer... I am just so far behind.
So, I am going to just back up D1 to D2, then
D2 to E2?
