Chalk is a unique action game by Joakim Sandberg which places emphasis on drawing to solve problems that the player will face in each of the six levels.

A collaborative effort between Terry Cavanagh, Hayden Scott-Baron and Alex May, the aim of Bullfist is to acquire as many points as you can in under one minute. This means guiding a herd of bulls, gathering their wounded mates, and destroying everything in their path before time runs out.

Some objects can only be destroyed when the herd is of a certain size. The special bullrage mode is activated when you've gathered six bulls in your stampede party, and you can extend the sequence by gathering more bulls before it ends.
