12 locks and keys

I put my spreadsheet brain into low-power mode for this one, and honestly that was the right call. 12 Locks and Keys is a singleplayer casual puzzle game set around a garden shed secured with, yes, exactly 12 locks. Your job is to wander a simple side-scrolling scene, solve small self-contained puzzles, collect each key, and unlock each lock in turn. The core loop is as literal as the title suggests. Mechanically, the game is as light as it gets. Interaction boils down to mouse-scrolling through a 2D scene, clicking on puzzle triggers, and slotting keys into their locks. There is no inventory management to speak of, no branching logic, no fail states with real consequences, and no timer pressure. The puzzle variety is modest: expect things like basic object manipulation, simple tile tasks, and some environmental clicking. One player-reported frustration worth flagging is a sliding tile puzzle that can reportedly reach an unsolvable state without a per-puzzle reset option, forcing a full restart if you scramble the board too aggressively. That is a real design gap for a game this short. The intended audience is genuinely young children or a parent wanting five minutes of screen-sharing with a toddler. The cartoony, hand-drawn 2D art is cheerful and reads well at a glance. The scene is a wholesome, colourful backyard setting. There is no violence, no failure screen, and very little friction. The whole run takes somewhere between a few minutes and 30 minutes depending on how much you poke around rather than simply press through. As a strategy and sim specialist, I can tell you this game offers zero decision depth. There is no build order, no AI to outmanoeuvre, no mod ecosystem to speak of, and no late-game complexity. The tutorial category is moot because the game barely needs one. Where it just about earns its slot: it works, it runs on ancient hardware, and for a very specific audience (pre-school age, total genre newcomers, parents hunting for something inoffensive to put in front of a small child) it delivers a tidy, self-contained experience with no edge content. The colourful art does its job. The apparent student-project origins of the development team show in the rough edges, but nothing is broken in a way that blocks completion for a careful player. For anyone older than about seven, or anyone who has touched a puzzle game before, the challenge ceiling arrives almost immediately and stays there.
