Strategy
Mouse
Work together to keep the large log balanced as you take turns bringing the cheese back to the mousehole. Look out for lemmings and trolls though , because they can make the bridge fall. In that case, mice can't do anything themselves, unless they landed on the pillar while the bridge was falling.
Shaman
Put a small plank below or through the large log with a centered red anchor. This keeps the large log from tipping or moving.
