Dave Sloan spent decades dreaming of making a game on the ZX Spectrum, and in 2021 he finally made Manic Mulholland with help from online communities and his son Nate. The positive response ignited a new obsession: going back to the 1980s to give his younger self the tools and knowledge to make even more Speccy platform games. Dave being Dave, he builds a time machine. Nate helps. An online guide provides the technical details. The fabric of time responds by going completely wrong. A metric system misunderstanding on the first test run sends both father and son into the time vortex. The only thing that will save them is collecting forty-two MacGuffinanium crystals.
