Dr. Jekyl and Mr. Hyde was released for the NES by Bandai in 1988 As the name suggests, is based on the famous novel by Robert Louis Stevenson. It is a fairly typical side-scrolling action game common in that era. While the concept is pretty unique, the actual game play does not live up to expectations.
As Dr. Jekyl, you are on your way to the church to get married. However, on the way you come into contact with various townspeople, some of whom for one reason or another annoy you. When your anger meter gets too high, you turn into Mr. Hyde and enter a demon dimension. This is where the "psyco-wave" touted on the box comes into play. Once you kill enough monsters, you turn back into Dr. Jekyl. The goal is to reach the church as Dr. Jekyl before or at the same time as Mr. Hyde.
There are six levels but oddly some of the levels differ between the Japanese and U.S. versions and some of the levels that are the same are in a different order. While it actually sounds pretty interesting, game play is frustrating and the graphics are lackluster.
If you do want to try this one, you'll have to track down an original cartridge or use emulation. There are no re-releases that I know of. However, you can skip this one without missing much. The concept is original but the execution leaves something to be desired.
