Jekyll Hakase no Houma ga Toki

About

Jekyll Hakase no Houma ga Toki is the Japanese original of the Famicom platformer later released in the West as Dr. Jekyll and Mr. Hyde. You play a scientist who transforms into a hulking alter ego to navigate shifting environments, using each form's strengths to solve puzzles and dodge hazards. The stages require precise timing and strategic use of transformations, with a focus on vertical platforming and environmental traps. This version differs from the international release with a reordered stage sequence and sharper difficulty spikes. Community analysis notes tighter controls and more punishing boss encounters compared to the Western edition. While it lacks some graphical polish of later ports, fans appreciate its lean design and the way it challenges players to adapt to its relentless pacing.
