YMMV / Jumpman

• Porting Disaster: While not exactly a terrible game, the C64 version of the original game suffers from long loading times, as well as having inferior audio and missing certain graphical effects (such as the transition to the next stage and the entire level crumbling down when you lose all your lives).
• Spiritual Successor: Raptisoft's Hap Hazard, which is basically this game but for modern computers and with a sci-fi theme. It even features a similar plot (trying to stop a location from getting blown up).
