A genuinely interesting mechanic trapped inside a rough, crash-prone package. F.E.X promises an escape puzzle built around one-way aging, but the execution rarely matches the concept.

I want to like F.E.X more than I do, because the core idea here is one of the more quietly haunting premises I've seen on a low-budget indie page. You play as T1M, a failed genetic experiment who ages in one direction only, moving from child to teen to adult to senior on a ticking biological clock. Holding a single key accelerates that process, which sounds like exactly the kind of intimate, irreversible mechanic that indie games do best. The tragedy of it, the way mortality is literally your resource bar, should land hard. Sometimes it does. In practice, the game is a top-down isometric escape across a multi-floor research facility, and the path you choose through it matters. Branching routes offer different enemy placements, collectibles, and fragments of story lore, which means a second playthrough will genuinely show you rooms you haven't seen. Collecting the scattered lore items is the difference between the basic ending and the one that earns the achievement called "You found out the truth." That kind of quiet completionist loop, discovering the full picture only if you go looking, is exactly the sort of handcrafted intent I respect in small games. But the friction is real and relentless. The isometric 3D perspective paired with 2D character sprites creates persistent spatial confusion, particularly when trying to pass through doors or trigger switches while a creature is closing in on you. T1M moves in only four cardinal directions, while enemies are free to track at any angle, so combat-adjacent encounters feel stacked against you by the geometry rather than by any meaningful design tension. The community has also flagged persistent crash issues during the tutorial sequence, which is about the worst place for a game to fall apart on a new player. Average playtime hovers around 72 minutes, which tells its own story about how many people bounced before reaching anything that felt rewarding. NonFictional Games built this out of real hardship, a small Mexican studio scraping through on government grants and sheer stubbornness, and that origin story deserves acknowledgment. There is genuine ambition in the aging mechanic, in the branching paths, in the checkpoint system that respawns you as an adult rather than trapping you in an unwinnable senior state. The bones of something atmospheric are here. The execution, though, is unpolished enough that only the most patient, concept-first players will find what they came for. Kai, Scout Team

GamerScout Verdict

Worth a look only for players who chase clever mechanics over polished execution and can forgive a genuinely rough technical state.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
