Solomon no Kagi: Oujo Rihita no Namida

The NES port of Solomon's Key, a puzzle game developed by Tecmo in 1986 for arcade on custom hardware based on the Z80 chipset. The game is generally recognized as one of the most difficult games to appear on the NES. The player, controlling a sorcerer known only as Dana must overcome unlimited enemy spawning, challenging level designs, a countdown timer, instant death from any physical contact with enemies, and limited ways to dispatch enemies.

Some levels contain pipes through which Dana can go, burning jars that melt ice or moving monsters instead of flames. There are ten worlds plus five secret worlds that contain ten levels. The first nine worlds can be played in any order. The tenth level of a world usually features a special challenge like moving flames or monsters and lava that is slowly rising from the bottom.

The aim of the game involves players extinguishing all fires in a level in order to proceed. They do this by creating and melting ice (in a Lode Runner style) or kicking ice onto the fires. This game also has a level editor (which may expose some bugs that substantially affect the game mechanics).
