The player must overcome unlimited enemy spawning, challenging level designs, a countdown timer, Dana's fragility, and limited ways to dispatch enemies. In addition, it's easy for players to unintentionally make levels impossible to clear while playing them. Solomon's Key also has many hidden items and secret levels that are hard to find which enhances the reward for playing. The ending also slightly changes depending on which secret levels the player finds and completes, if any. The main character, Dana is sent to retrieve "Solomon's Key" to restore the world to light from demons that were accidentally released. The object of the game is to advance through the 50 rooms of "Constellation Space" by acquiring a key to the door that leads to the next room before a timer runs out. The game incorporates elements of the platform shooter genre. Dana can run, jump, create or destroy orange blocks adjacent to him as well as create fireballs to destroy demons. The orange blocks can also be destroyed by jumping into them twice. Along the way Dana can acquire items to upgrade his firepower and extra lives as well as item that award bonus points and unlock hidden rooms. With certain items, Dana must make, then break blocks (sometimes in a certain manner) to make these appear. Fire 'n' Ice is the sequel to Solomon's Key. Чувак в костюме леприкона бегает по лабиринту. Он может прыгать, стрелять (если подобраны "заряды"), а также создавать и уничтожать кирпичные блоки. Требуется за отведенное время добраться до двери, для перехода в следующий уровень, не попавшись в лапы к различным монстрам. Английская и японская версии
