The hero of the game TermiStone went into underground caves to find golden magic balls. At each level you need to get to the ball, overcoming various obstacles. The hero can change his essence, becoming either ice or fire, but for this he needs to find the corresponding magic spheres. At the same time, you need to be careful not to fall into traps made of ice or fire. Each new level will bring new challenges and obstacles that must be overcome, including using logic in TermiStone.
