Every workplace has that one coworker who never complains, never clocks out early, never once asks for a raise, and the reason turns out to have nothing to do with dedication. That coworker is a biot, one of the biologically engineered humanoids who make up much of the workforce in the year 2066, and this particular one, designated Unit 532 in whatever paperwork tracks him, spends his days as an activate-on-request companion at an adult entertainment venue called Dollhouse. HeartCoreDev, a Canadian studio led by writer and producer Irlana, built Synthetic Lover around the unsettling mechanics of that job description, a servant designed to sit inert as a doll until summoned, his self-awareness deliberately sealed away by whoever built him. That routine holds until an opportunistic thief crosses his path carrying a device that undoes exactly what his makers meant to keep locked down.
From there the story splits, sharing its opening stretch before branching into two separate paths built around two distinct men willing to help him figure out what’s happening to him, Bastian and Terrance. Choices along either path shape how individual scenes play out and how things ultimately land by the end, but the fork itself happens early and stays put, meaning the route I picked determined almost everything that followed rather than something I could steer moment to moment. Bastian pulls the story toward the city’s rougher underworld, a brash, charismatic bartender whose connections and motivations for carrying that strange device in the first place only come into focus gradually, while Terrance’s route runs cooler and more guarded on the surface, a business-like, buttoned-up presence whose composure only cracks in response to real patience rather than charm. Riko, a Dollhouse maintenance technician who calls herself a biot doctor, rounds out the supporting cast with a real fascination for the biots she’s meant to be servicing rather than fixing. A Kickstarter campaign that funded the game back in the summer of 2019 unlocked stretch goals adding two further paths beyond just Bastian and Terrance individually, a combined Threesome route and a separate Malfunctioning Biot storyline, along with extra CGs woven into each existing route.
Watching a character built entirely around obedience start second-guessing his own programming gave the early chapters real tension, especially once it became clear how much of his old life he’d have to unlearn just to function outside Dollhouse’s walls. Both Bastian and Terrance get their own musical identity within the game’s score, a small but telling sign of how seriously the writing treats each relationship as its own distinct arc rather than a palette-swapped retread of the other.
HeartCoreDev has pointed to Blade Runner, Westworld, Ai no Kusabi, and Starfighter: Eclipse as touchstones behind the world here, and that lineage shows in how matter-of-fact the setting treats artificial people as an exploited underclass rather than a novelty. None of that inspiration reads as pastiche, since the specific mechanics of the Dollhouse system and the organization enforcing it feel built for this story rather than borrowed wholesale from any one influence.
Character illustrations and CGs came from Unhlyghst, with Jupalour, credited elsewhere as Juan Pablo Lozano, handling the backgrounds and environmental conceptual work, at least four distinct bathroom and shower settings among them, since five separate scenes across the game take place there, not all of them intimate despite how that sounds on paper. RedRobotix composed eleven of the soundtrack’s fourteen tracks, with Unglyghst contributing three more, and between them the score covers a surprising amount of emotional ground, from a main theme setting the tone up front to individual character pieces for Bastian and Terrance, down to mood-specific ambient cues for tension, sorrow, and quieter moments alike. That level of granularity in a scoring approach is rare for a game this size, and it paid off every time a scene’s mood shifted and the music shifted right alongside it.
Full English voice acting carries every major line of dialogue, and the game backs that up with a Ren’Py self-voicing mode that reads menus and unvoiced text aloud for screen reader users, a real thoughtful accessibility choice that a lot of bigger productions skip entirely. Hearing the protagonist’s flat, dutiful delivery slowly gain inflection as his emotions come online did more to sell his arc than the dialogue alone would have.
None of that unlearning happens in a vacuum either, since the organization that built him has its own reasons for wanting him back under control, and that pressure kept the back half of the story from settling into a straightforward romance once the initial discovery wears off. What actually happens across the game’s seven endings stays out of scope here, but the weight of choosing between staying hidden and actually living caught me more off guard than I expected going in.
The Kickstarter campaign that made all of this possible ran from June 11 to July 23, 2019, closing at 101 percent of its $11,200 Canadian dollar goal thanks to 233 backers averaging roughly $48.61 apiece, funding that went toward a digital and physical artbook alongside the extra routes mentioned earlier. Irlana herself is Ukrainian, based in Canada for two decades by the time the game came out, and the finished release, four years in the making from that initial Kickstarter, landed on well over 138,000 words spread across 57 unique CGs and more than 100 distinct backgrounds, backing up its two core routes with eighteen separate Steam achievements to chase. Synthetic Lover first launched through itch.io on December 16, 2021, before reaching Steam and GOG that January and later PS4, PS5, and Switch in December 2023 through Eastasiasoft and Male Doll Publishing. An official Choice Guide and a standalone soundtrack release followed shortly after launch too, sold separately for anyone who wanted either one without necessarily needing the other. The base release stays at a PG-13 level, with a separate free patch available for players who want the fully explicit version, a detail worth knowing going in but not one that changes what the underlying story is actually about. HeartCoreDev has since moved on to a new project of their own, The Symbiant, a space-set BL visual novel from Irlana and a collaborator credited as Fable, which suggests this studio sees Synthetic Lover as a foundation to build on rather than a one-off.
Verdict
Synthetic Lover takes a well worn science fiction question, whether a manufactured person can earn the right to feel, and gives it real weight through two distinct men worth building a whole route around. Bastian and Terrance’s individually scored themes and a real accessible voiced presentation show a level of craft that punches well above the game’s modest scope, and a Kickstarter-funded expansion into additional routes gives it more to explore than its base premise alone would suggest. It’s a thoughtful, well-produced romance that never lets its sci-fi backdrop overshadow the person at its center.
