Control a cartoon dog babysitting an oblivious sleepwalker across rooftops, zoos, and crypts. A genuine early-90s puzzle-platformer oddity with more charm than polish.

My strategy brain kept trying to pre-plan routes, and Sleepwalker kept punishing me for it. That's the honest summary of spending time with this early-90s DOS/Amiga port, now quietly available on PC via Ziggurat's catalog of preserved classics. The core mechanic is genuinely clever: you control Ralph the dog, not Lee the sleepwalker. Lee marches autonomously in whatever direction he's facing, and your entire job is to reshape the environment around his oblivious path before he walks off a rooftop or into a zoo enclosure. It's indirect control as a design philosophy, and in 1993 that was a sharp idea. The six main parallax-scrolling levels span city rooftops, a crypt, a construction site, and other locations that give Ralph a rotating set of hazards to manage. Ralph can punch enemies out of Lee's way, bridge gaps, and puff himself up with helium to float over obstacles. Between the main stages sit five bonus dream sequences where Ralph collects tokens and triggers scenes reflecting his private thoughts about Lee's night-time wandering. The comedic framing holds up reasonably well. What doesn't hold up as cleanly is the difficulty tuning. Retro community sentiment from Amiga and C64 era players is split sharply: half describe it as charming and underrated, the other half call it colourful but fundamentally frustrating to control under pressure. Both camps are right. The sleep-meter bar at the top of the screen, which empties whenever Lee takes a hit or gets startled, turns several later sections into a tense race against a timer you can't fully control, and that friction feels less like designed tension and more like a product of its era. For a strategy-minded player the appeal is real but limited. There's genuine forward-thinking required: you have to anticipate Lee's next few steps and position Ralph proactively, which scratches the same pre-planning itch as a light puzzle game. But the AI (such as it is) is deterministic rather than dynamic, and there's no build variety, no upgrade path, and no difficulty scaling. You get what 1993 gave you. The COMIC letter collectibles scattered across stages offer a small secondary objective, and completing the full set rewards an extra life, but that's the ceiling of optional content. The PC version is a DOS port delivered through DOSBox or equivalent, so expect the compatibility caveats that come with any Ziggurat retrosale. No modern control remapping, no widescreen, no quality-of-life additions. The five existing user reviews on Steam are too sparse to draw firm conclusions from, and there's no Metacritic entry. What broader retro coverage exists suggests the Amiga original was the definitive version graphically, with richer FMV sequences and cleaner sprites, so PC players are getting a slightly pared-back experience. That said, the core puzzle-platformer loop is intact and functional. If you've never encountered the game, the concept is novel enough to warrant an afternoon. If you're hoping for a deep or replayable experience, this is a one-run curiosity, not a catalogue staple. Diego, Scout Team
