Smus is a platform game. The hero of the game was kidnapped by Ice Baron. The player must help him escape from the old ruins. There are nearly 250 rooms to overcome. In each of them, the protagonist encounters baron knights, Indians and birds. The small dragon dies after contact with poisoned water and spikes. An additional complication are the moving platforms and the time limit - exactly 9999 seconds. Blue buttons allow to replenish the fire and open the bars blocking the way.
