Solomon no Kagi

Solomon's Key is a puzzle game developed by Tecmo in 1986 for an arcade release on custom hardware based on the Z80 chipset. It was ported to multiple systems including the Nintendo Entertainment System and Commodore 64.

There are 64 levels in total, of which 15 are secret and one is the final level. The main 48 levels are divided into groups of 4 with one group for each of the 12 Zodiac constellation (in order, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces). The final level is called Solomon's room. Each constellation has a secret bonus room which can only be accessed by finding a seal for the constellation in the last room of the group. The other three levels are Page of Time, Page of Space and the Princess Room, which occur only if the player has acquired the hidden Seals of Solomon.

Best ending shown, which requires collecting all Solomon's seals, all constellation seals and both pages. I also attached the other endings at the end of the video, and also revealed the locations of every item where possible.
