David Szymanski’s Iron Lung is a brilliant piece of short-form indie horror, but it is intentionally uncomfortable. You sit in a tiny room, match X and Y coordinates on a paper map, flip heavy levers, and click a camera button to get a low-res image of whatever is lurking outside in the dark blood ocean.

There are no microtransactions, no multiplayer lobbies, and no predatory retention mechanics. It is pure single-player game design that treats the player's imagination as the main source of terror. That said, it is profoundly dark—both literally and narratively—and not built for kids looking for lighthearted fun.
