This 1995, Japan-only release is a game that begins fairly un-remarkably, but quickly opens up to become one of the most interesting and visually exciting action platform games on the SNES.
The fantasy horror theme in King of Demons (aka Majyūō) means plenty of gruesome set pieces, some of which could have surely fallen foul of the censorious Nintendo of America (and maybe Europe too).
There are fan-made English language versions around, should you decide to play it. It is definitely worth a look-see, even if it is a little on the tough side.
