Anybody can be the Wolf. At the same time, not all the shapes that are similar, are necessarily him. In your attempts, you need a keen eye and a good nose for trouble to spot the different shapes the Wolf might take, while avoiding throwing accusations at the villagers.
There are 3 levels of difficulty in the game. Keep in mind that the game was made in under 24 hours from scratch. No assets were used, except the sound-design. Unfortunately the day was far too sunny to record thunderstorms and rain.
