Boulders or Rolling Stone is a minigame which appeared in Hugo 6 and Hugo Classic 4, being almost completely remade for the boss battles in Hugo Troll Race 2.
Gameplay[]
Hugo flees from enormous boulders (towards the screen), avoiding obstacles such as dead ends, tree roots and lava pits. If Hugo runs out of time, a powder barrel blows up and destroys the rope bridge that leads to Scylla's lair, but he also has to find a clue on how to open the gate to it.
