A quiet, oddly personal 2D action game from a solo Chinese dev that most of the internet missed entirely. Worth knowing about if you have a soft spot for underground worlds and hand-built charm.

I stumbled into The Underground Watcher the way you stumble into a half-lit room at a night market - something about the setup felt handmade and a little off-centre in the best possible way. Yima VLG. is a one-person studio, and this game wears that fact openly: rough translation, modest scope, and a strange sincerity that bigger productions can rarely fake. You play as Xu Sisi, a young woman who takes a short-term government patrol job and ends up working underground, literally. The gameplay sits in an unusual lane: a 2D side-scroller that deliberately strips out most platforming (the developer calls it "almost no-place-to-jump"), so the focus lands entirely on movement through the underground environment, a simplified combat skill list, and a basement upgrade loop funded by monster kills. It is less Hollow Knight and more a quiet action RPG in miniature - patrol a zone, fight what you find, spend your earnings improving your office down in the sewer, push the story forward. There is something meditative about that rhythm once it clicks. The story is where Yima VLG. is most clearly reaching for something personal. Sisi's past is unspooled gradually through encounters on the job, and the tone sits somewhere between slice-of-life and low-key mystery. The English localisation is imperfect - phrasing is occasionally awkward - but it never becomes a wall. For players who can appreciate a developer communicating through a second or third language, the intent comes through clearly enough. Steam players who found their way here gave it a strong reception among the small pool who reviewed it, with community members calling the story genuinely fun and entertaining all the way through, and noting it probably deserves more attention than it has received. The caveats are real. The skill list is short. The production values signal a solo debut, not a polished studio release. If you come expecting tight combat feel or a rich upgrade tree, the basement system will feel thin. The game seems designed for a specific kind of player: someone who finds something worthwhile in a compact, authored experience that knows its own boundaries and stays inside them. At its length - sessions feel short by design - it never outstays its welcome, which is a discipline a lot of larger games fail to show. For me, the quiet underground atmosphere and the sense that one person built this world for a reason is enough to make it worth an afternoon. It fits into a tradition of small Chinese indie games that never quite reach Western audiences, and that is a small shame. If you already keep a folder of obscure one-dev Steam releases, this belongs in it. Kai, Scout Team

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.
