A few questions:
1. Can the group position themselves in the green box at one corner so the tank gets knockbacked the diagonal length of the box? Or is the knockback distance too long?
2. What does the group do when the left-most 1st space is red? It seems like if that is the case the group has 3 options: (A) /stuck (B) see if right-most 1st space is green or (C) attempt to progress down middle and hope the knockback doesn't knock the tank out of the diagonal length of the box.
Well if the leftmost space is always green I think we can assume that the change is intended... If not...
Does the fire start AFTER or BEFORE the first defusal? Cause if it's after then the group can just get the first probe without standing on the actual minefield
