Nightmare Fuel / Dr. Jekyll and Mr. Hyde (NES)

• One of the monsters in Hyde's stage is a hopping brain with legs.
• The game's second ending, earned by reaching Level 6 as Jekyll and then proceeding to the end as Hyde. Hyde then fights a boss at the church, and, upon beating it, turns back into Jekyll. Jekyll's able to reach the church unhindered and an extended cutscene of the wedding plays. "END" appears when the screen fades out after bride and groom kiss. However, after waiting a while, the music will abruptly stop and the sound effect for the bomb is played. When the bomb "explodes", lightning flashes, the word "END" appears reversed, and Mr. Hyde appears as a red silhouette with a giant cross embedded into his back. Like everything else about the game, the extended ending is unexplained, leaving it ambiguous as to whether or not it can be considered a "good" or "bad" ending. Hyde's silhouette in the second ending comes out of nowhere, and given what happens to Dr. Jekyll in the book, it can be implied that Hyde still "lives", or worse, that the demon he killed took over the Hyde personality. The lighter explanation is that the cross represents Jekyll finally "ending" Hyde by getting married. This video suggests the latter is a good ending.
